Breast Reconstruction After Mastectomy - Dr Chrysopoulo Radio Interview

It was an absolute pleasure to talk to DeLeon and Travis on "DeLeon Dialogue" last night.

Breast cancer survivor DeLeon and cervical cancer survivor Travis talk frankly with their guests about quality of life as cancer survivors in remission. They discuss side effects, spirituality, mastectomy, sexuality, health and wellness, self-esteem, food, exercise, relationships, and everything else in between.

Last night the one-hour show was about "breast reconstruction after mastectomy". We managed to cover a lot of ground - we talked about the various cutting edge breast reconstruction options currently available, breast implants, the impact of radiation therapy on reconstruction, recovery from surgery, and insurance coverage for reconstruction.

When is Prophylactic Mastectomy The Right Choice?

Having breast cancer in one breast increases a woman's chances of getting breast cancer in the second breast at some point in her lifetime. A study in the March issue of Cancer addresses a question which women facing mastectomy for breast cancer have been asking doctors for years.... should I have my other ("good") breast removed as well to decrease my risk of future breast cancer in the other breast? Here's the study abstract....

"Predictors of contralateral breast cancer in patients with unilateral breast cancer undergoing contralateral prophylactic mastectomy."
Min Yi, Funda Meric-Bernstam, Lavinia P. Middleton, et al. CANCER Print Issue Date: March 1, 2009

BACKGROUND:
Although contralateral prophylactic mastectomy (CPM) reduced the risk of contralateral breast cancer in unilateral breast cancer patients, it was difficult to predict which patients were most likely to benefit from the procedure. The objective of this study was to identify the clinicopathologic factors that predict contralateral breast cancer and thereby inform decisions regarding performing CPM in unilateral breast cancer patients.

METHODS:
A total of 542 unilateral breast cancer patients who underwent CPM at The University of Texas M. D. Anderson Cancer Center from January 2000 to April 2007 were included in the current study. A logistic regression analysis was used to identify clinicopathologic factors that predict contralateral breast cancer.

RESULTS:
Of the 542 patients included in this study, 25 (5%) had an occult malignancy in the contralateral breast. Eighty-two patients (15%) had moderate-risk to high-risk histologic findings identified at final pathologic evaluation of the contralateral breast. Multivariate analysis revealed that 3 independent factors predicted malignancy in the contralateral breast: an ipsilateral invasive lobular histology, an ipsilateral multicentric tumor, and a 5-year Gail risk 1.67%. Multivariate analysis also revealed that an age 50 years at the time of the initial cancer diagnosis and an additional ipsilateral moderate-risk to high-risk pathology were independent predictors of moderate-risk to high-risk histologic findings in the contralateral breast.

CONCLUSIONS:
The findings indicated that CPM may be a rational choice for breast cancer patients who have a 5-year Gail risk 1.67%, an additional ipsilateral moderate-risk to high-risk pathology, an ipsilateral multicentric tumor, or an ipsilateral tumor of invasive lobular histology.

*****

So what does all this mean?

This study basically concludes that prophylactic (ie preventive) mastectomy should be recommended to breast cancer patients in the following situations:

1) the breast cancer is particularly aggressive or invasive

2) the biopsy pathology report shows high risk histology (such as "invasive lobular" disease)

3) there are multiple tumors in the same breast

4) a 5-year Gail risk of at least 1.67 - The "Gail risk" assesses a woman's risk of developing breast cancer by looking at a number of health factors including her medical history, race, age and more.

5) age 50 or older at the time of the first breast cancer diagnosis

This study is helpful. I'd like to expand a little on the effect age has on risk of future disease. Many doctors (including myself) recommend prophylactic mastectomy to young women, particularly if they have a family history of breast cancer, as these women have the highest overall risk of getting another cancer in their lifetime. Previous studies have shown that breast cancer patients have close to a 1% risk of another cancer per year. This risk is cumulative, in other words, it adds up: 1 % risk after 1 year, 10% risk after 10 years, 30% after 30 years, and so on. This cumulative risk is important to remember.

While I applaud this study and think it's results are very useful, I also think it is imperative that doctors remember the primary indication for prophylactic mastectomy: the patient's wishes. Breast cancer is such a devastating disease both physically and emotionally. We can educate our patients all we want about study results but we must not forget the erosive nature of anxiety over the possibility of a second breast cancer in the future. If one of my patients wants a prophylactic mastectomy even after discussing the studies, that's good enough for me.

Breast Reconstruction Surgery - Part I - Tissue Expanders, Breast Implants and Alloderm

This posting is the first of a 3-part series on breast reconstructive surgery discussing the reconstructive options available to women facing mastectomy for breast cancer.

Every woman has a right to breast reconstruction. This has now actually become a federal mandate and insurance companies are required to pay for all types of breast reconstruction by law. Having said that it is also important to remember that it’s not up to the health insuranc carrier to decide which reconstruction a patient receives. That’s determined by the patient and her surgeons.

Breast reconstruction is not a form of cosmetic surgery – it restores something that nature has provided but cancer has taken away. There is also no age limit – as long as there are no medical conditions that render the surgery unsafe and the breast cancer is diagnosed at an early enough stage, most women are candidates.

Breast reconstruction can be performed as an “immediate” or “delayed” procedure. As the term implies, immediate reconstruction is performed immediately after the mastectomy while the patient is still under anesthesia. Once the general surgeon has completed the mastectomy the plastic surgeon begins creating the new breast. Advantages of this approach include the option of preserving most of the breast skin (“skin-sparing mastectomy”) and a shorter scar. The patient also wakes up “complete” and avoids the experience of a flat chest. Immediate reconstruction generally provides far superior cosmetic results.

Delayed reconstruction generally takes place several months following mastectomy. Patients required to undergo radiation after mastectomy may be advised to delay reconstruction in order to achieve the best results. This delay may last several months in order to allow the tissues to recover as much as possible from the radiotherapy.

There are several reconstructive options for women to choose from, ranging from breast implants to “autologous” techniques using the patient's own tissue to recreate a more “natural”, warm, soft breast. The nipple and areola can also be recreated.

Tissue Expanders and Breast Implant Reconstruction

This is the most common method of reconstructive breast surgery currently being used in the United States. Most surgeons perform this is a two-stage procedure. The tissue expander is essentially a temporary breast implant which can be placed either at the same time as the mastectomy or after the mastectomy has healed. The expander is used to stretch the skin envelope and recreate the size of breast the patient wants. The expander is ultimately replaced by a permanent implant (saline or silicone) at a separate procedure several months later.

Some patients undergoing immediate breast reconstruction are candidates for one-step breast implant reconstruction whereby a permanent implant is inserted at the time of the mastectomy and the patient avoids going through the whole expansion process. In the one-step implant reconstruction the implant is completely covered by the pectoralis muscle and Alloderm (a cadaveric acellular dermal graft). This is specially treated skin from a cadaver that is used to provide a sling and coverage of the lower part of the implant.

Two types of implants are available to patients: saline and silicone. There are many opinions regarding both types of implants and it is advised that you speak with your surgeon as to which implant would be best for you. Patients who undergo implant reconstruction should be aware that their breast implants may need to be replaced at a future date.

Implant reconstruction can be the best option for some patients. However, tissue expanders and implants can be fraught with complications long-term, particularly if the patient has had or is going to have radiation therapy as part of her cancer treatments. For these reasons, many surgeons and patients prefer autologous reconstruction, i.e. reconstruction using the patient's own tissue taken from another part of the body. These will be discussed in upcoming posts.

Breast Reconstruction Surgery - Part II - Muscle Flap Reconstruction

Women interested in breast reconstruction after mastectomy have several reconstruction options to choose from. In Part I of this series we discussed tissue expanders, breast implants and Alloderm.

Though implant reconstruction remains the most common method of breast reconstruction in the US, many women are now steering away from this option, opting instead to use their own tissue for more “natural” results. Muscle flaps have, until fairly recently, been the only choice available for these tissue reconstructions. The most commonly offered muscle flaps are the latissimus and TRAM flap procedures.

Latissimus Dorsi Flap:

The latissimus procedure uses muscle from the back of the shoulder blade which is brought around to the breast mound to help create a new breast. During the procedure a section of skin, fat and muscle is detached from the back and brought to the breast area.

Many patients also need a tissue expander placed under the muscle flap in order to obtain a satisfactory result. The expander is replaced by a permanent implant at a second procedure down the line.

Patients will have a scar on their back shoulder region that can sometimes be seen through a tank top, swimsuit or sundress. The upper back can be numb or sore for a few following this procedure until the nerves grow back and the incisions are completely healed.

Women who are very active in sports should know that this procedure can reduce ability to participate in activities like golf, climbing, swimming, or tennis.

TRAM (Transverse Rectus Abdominis Myocutaneous) Flap:

The TRAM flap was the first procedure to describe use of one of the rectus abdominis muscles (sit-up muscles) for breast reconstruction. This procedure begins with an incision from hip to hip rather like a “tummy-tuck”.

A "flap" of skin, fat and one of the patient's abdominal muscles is typically tunneled under the skin to the chest to create a new breast. This is known as a pedicled TRAM flap. Recovery from the TRAM flap procedure can be difficult and painful and there is a risk of abdominal bulging (or “pooching”) and even hernia. Long-term, the patient has to adapt to the loss of some abdominal strength (up to 20%) which most active patients will notice.

In cases where both breasts are being reconstructed, both abdominal muscles are sacrificed and transferred to the chest (one for each breast). The loss of abdominal strength in these situations is far greater and very significant.

Over the years and with the introduction of microsurgery, the procedure has evolved several times with each modification preserving more and more abdominal muscle. This has made postoperative recovery a little easier and has decreased the potential for abdominal complications somewhat.

The latest evolution in breast reconstruction is  “perforator flap surgery”. These techniques use skin and fat from various parts of the body. Since no muscle is sacrificed recovery is much easier and muscle strength and function are preserved long-term. These techniques will be discussed in Part III of this breast reconstruction series.

Breast Reconstruction Surgery - Part III - Perforator Flap Reconstruction

The ideal breast reconstruction technique is one which allows reconstruction of a “natural”, warm, soft breast with the least impact on the patient’s body. While breast reconstruction with stem cells may not be too far off, until it becomes a reality we are limited to using the patient’s own tissue to achieve these goals. As discussed in the previous posts in this breast reconstruction series, until fairly recently the only “tissue reconstruction” options involved sacrificing muscle. This made recovery from the surgery difficult and painful, not to mention the risk of long-term muscle function loss and weakness.

Perforator flap techniques use skin and fat from various parts of the body. All muscles are preserved. Since no muscle is sacrificed recovery is much easier and muscle strength and function are preserved long-term. The downside to these procedures is that they are technically much more demanding than other breast reconstruction techniques and require microsurgical expertise. For this reason they are not offered by many plastic surgeons and patients must be prepared to travel when choosing these procedures.

DIEP (Deep Inferior Epigastric Perforator) Flap

The DIEP flap is the latest evolution of the TRAM flap (discussed in Part II) and represents today's gold standard in breast reconstruction. The DIEP flap procedure is similar to the TRAM flap but only requires the removal of skin and fat. NO MUSCLE is sacrificed. The blood vessels required to keep the tissue alive lay just beneath the abdominal muscle. Therefore, a small incision is made in the abdominal muscle in order to dissect the vessels and microsurgery is required to reattach the blood vessels to the chest area.

Even though an incision is made in the abdominal muscle NO abdominal muscle is removed or transferred to the breast in the DIEP flap procedure. As a result, patients do not have to sacrifice their abdominal strength and they experience less pain and a much quicker recovery. The risk of abdominal bulging and hernia is also very small.

The DIEP flap was first described in the early 1990's but has remained much less popular than the TRAM flap among plastic surgeons, presumably because of the increased complexity and difficulty of the procedure compared to the TRAM.

So the advantages of the DIEP flap are multiple: it uses living tissue to recreate a breast that often looks and feels like a normal breast; abdominal strength is not affected; the risk of bulging or hernias is significantly reduced; and, like the TRAM flap, the patient benefits from a simultaneous “tummy-tuck”.

The DIEP flap is a very technically demanding operation but the benefits are tremendous for the patient, especially when performed at the same time as a skin-sparing mastectomy.

SIEA (Superficial Inferior Epigastric Artery) Flap

The SIEA flap procedure is very similar to the DIEP flap procedure. The main difference between the SIEA and DIEP is the artery used for blood flow supply to the reconstructed breast. The SIEA arteries are generally found in the fatty tissue just below skin.

As in the DIEP the SIEA flap reconstruction does not sacrifice the abdominal muscle and only uses the patient's skin and fat to reconstruct the breast. While the SIEA flap procedure is similar to the DIEP it is used less frequently since less than 20% of patients have the anatomy required to allow this procedure.

GAP (Gluteal Artery Perforator) Flap

Women who do not have an adequate amount of abdominal tissue for reconstruction may be eligible for the GAP flap. This procedure uses excess skin and fat from the gluteal or buttock region. Fat and skin from either the upper or lower buttock region can be used and microsurgically transplanted to the chest.

Once again, no muscle is sacrificed. Incisions can generally be hidden by most underwear. If a patient requires a bilateral reconstruction with GAP flaps most surgeons prefer to only perform one side at a time. It is important to discuss this possibility with your surgeon.

Advantages of the GAP flap include: a scar that is generally hidden with underwear or swimsuits, and no loss of muscle function or strength.

Other Breast Reconstruction Options:

TUG (Transverse Upper Gracilis) Flap

Like the GAP flap, the TUG flap is an option in cases where there is not enough lower abdominal tissue to reconstruct the breast(s). The TUG procedure uses the upper part of the inner thigh; skin, fat and a small amount of muscle are disconnected and transferred to the chest to create the new breast. The patient benefits from a simultaneous inner thigh lift. Once again, this procedure is not widely available due to its complexity and need for microsurgical expertise.

It is important to realize that whichever method of reconstruction is used, the vast majority of women will require 2 or even 3 procedures for the optimal cosmetic result. Each procedure is typically separated by several weeks. The entire reconstructive process, regardless of the method of reconstruction, can therefore take several months to complete. However, breast reconstruction does NOT typically complicate or delay cancer treatment such as chemotherapy.

With all this in mind and also remembering the superior cosmetic results associated with immediate breast reconstruction (reconstruction performed at the same time as mastectomy), it is recommended that women discuss their reconstructive options with a plastic surgeon specializing in breast reconstruction before undergoing mastectomy whenever possible.

Breast Reconstruction With Tissue Much Safer Than Implants When Radiation Planned After Mastectomy

A study published in the November issue of the International Journal of Radiation Oncology*Biology*Physics examined the effect of radiation therapy on different methods of immediate breast reconstruction surgery. For breast cancer patients who receive radiation therapy after a mastectomy and immediate breast reconstruction, autologous tissue reconstruction (ie reconstruction using their own tissue) provides fewer long-term complications and superior cosmetic results than breast reconstruction with a tissue expander and subsequent breast implant.

Many women choose to undergo breast reconstruction surgery at the same time as their mastectomy procedure (under the same anesthetic). This avoids many of the psycho-social issues women face when dealing with a flat chest after mastectomy alone. However, frequently radiation can negatively affect the outcome of reconstruction and increase the risk of long-term complications.

Radiation therapy is increasingly becoming the standard of care for high-risk breast cancer patients after mastectomy in an attempt to decrease local cancer recurrence. However, this can cause a problem for both patients and their radiation oncologists.

Researchers at the Department of Radiation Oncology at Long Island Radiation Therapy in Garden City, N.Y., the Department of Surgery at Long Island Jewish Hospital in New Hyde Park, N.Y., the Department of Surgery at North Shore University Hospital in Manhasset, N.Y., and the Department of Surgery at Winthrop University Hospital in Mineola, N.Y., looked at whether the type of reconstruction performed in women receiving radiation after a mastectomy had an impact on their long-term outcomes.

Two general types of breast reconstruction are available for patients facing mastectomy for breast cancer: autologous tissue reconstruction utilizing the patient's own tissue (eg DIEP flap, GAP flap, TRAM flap, or latissimus flap) transferred to the chest to recreate the breast(s); and tissue expander/implant reconstruction which involves placement of an inflatable tissue expander (temporary saline implant) and exchange for a permanent implant (saline or silicone) at a separate procedure later on.

This study involved the largest reported series of patients who sequentially underwent mastectomy, immediate reconstruction and postmastectomy radiation therapy. Ninety-two patients were observed for a period of 38 months following breast reconstruction and radiation therapy.

Researchers found that autologous breast reconstruction is better tolerated by breast cancer patients because it is associated with fewer long-term complications and better cosmetic results than tissue expander/implant reconstruction.

None of the 23 patients reconstructed with their own tissue required further surgery while 33% of tissue expander/implant patients needed surgery to correct a problem with their reconstruction. Eighty-three percent of autologous reconstruction patients reported acceptable cosmetic results, as opposed to only 54% of implant patients.

"This study is useful for patients who are candidates for either [method of reconstruction] and are making a decision with regards to reconstruction technique," Jigna Jhaveri, M.D., lead author of the study and a radiation oncologist at Advanced Radiation Centers of New York in Hauppauge, N.Y., said. "Our study provides evidence that patients who undergo autologous tissue reconstruction and radiation therapy have fewer long term complications and better cosmetic outcomes than those who undergo tissue expander/implant reconstruction and radiation therapy."

*****

Here's my take....

While some plastic surgeons will disagree with this statement I strongly believe that breast implants and radiation therapy do not get along (at all). I feel the complication rate in implant-reconstructed women receiving radiation therapy is very high, particularly long-term. The handful of women that "do fine" in the short-term will very frequently end up with hard, uncomfortable breasts as the irradiated tissue firms-up over time and squeezes down on the implant. In my opinion the re-operation rate is too high for tissue expander/implant reconstruction to be offered as a routine option when radiation is on the table. This study confirms that breast reconstruction using the patient's own tissue is far safer than tissue expander/implant reconstruction in women facing radiation therapy after mastectomy.

Breast Cancer Recurrence Not Related To Method Of Breast Reconstruction

One of my breast cancer patients called me today. She recently underwent bilateral mastectomies and immediate breast reconstruction with DIEP flaps. She recovered very well from the surgery but unfortunately her pathology results showed that she had cancer extending almost to the edge of the mastectomy specimen. The exact medical jargon used by the pathologist was.... "invasive carcinoma extending to 1mm from the margin". She also had DCIS (ductal carcinoma in situ) "extending to 0.2mm from the margin."

From a purist's perspective, these results still represent "clear margins". In other words, no tumor was found at the edge of the mastectomy specimen so there is no reason to believe there is any cancer left in my patient's breast. BUT, it's very close and that is certainly worrisome.

She called me today because she visited with her oncologist (cancer doc) and a radiation oncologist (cancer doc specializing in radiotherapy) and radiation therapy was recommended (in addition to the planned chemotherapy).

She explained to the radiation oncologist that she was worried the radiation therapy would ruin her DIEP flap reconstruction. She is right to be fearful of this - patients undergoing radiation therapy after an autologous reconstruction (ie a reconstruction using their own tissue) have a 28% risk of needing further surgery to correct asymmetry caused by the radiation changes (usually firming and shrinking) of the irradiated breast.

The response she received from the radiation oncologist baffled me (and is actually the reason behind this blogpost)...... "DIEP flap? What's a DIEP flap?.... if you'd had a TRAM flap then you wouldn't be needing radiation".

What?

This is a ridiculous statement. Let me clarify why...

This lady is being recommended radiation therapy as an insurance policy to decrease the risk of local recurrence (cancer coming back in the same breast). This is a consequence of her "near margins" which in turn are a result of the mastectomy specimen. Obviously the mastectomy was completed before the reconstruction was even started. If this lady had only had the mastectomy (without reconstruction) the margins would be the same. The breast reconstruction, and moreover, the type of breast reconstruction has absolutely nothing to do with it. The margins, the pathologist reading and the recommendation for radiation therapy would have been exactly the same whether reconstruction was performed or not.

So what's the take home message if you're considering breast reconstruction surgery? Choose whichever method of reconstruction is best for you. Your decision will not influence the likelihood of your cancer coming back in any way. The risk of cancer recurrence is related to the characteristics of the cancer itself and the mastectomy margins, not the method of reconstruction.

Avoiding Denervation of Abdominal Muscles during DIEP Flap Breast Reconstruction Surgery

The following interesting article was published in the "Plastic and Reconstructive Surgery" journal this month.....

Avoiding Denervation of Rectus Abdominis in DIEP Flap Harvest II: An Intraoperative Assessment of the Nerves to Rectus
by Rozen W, Ashton M, Kiil B, et al.
Plastic and Reconstructive Surgery:Volume 122(5) November 2008 pp 1321-1325.

Background: The deep inferior epigastric artery perforator (DIEP) flap aims to reduce donor-site morbidity by minimizing rectus muscle damage; however, damage to motor nerves during perforator dissection may denervate rectus muscle. Although cadaveric research has demonstrated that individual nerves do not arise from single spinal cord segments and are not distributed segmentally, the functional distribution of individual nerves remains unknown. Using intraoperative nerve stimulation, the current study describes the motor distribution of individual nerves supplying the rectus abdominis, providing a guide to nerve dissection during DIEP flap harvest.

Methods: Twenty rectus abdominis muscles in 17 patients undergoing reconstructive surgery involving rectus abdominis (DIEP, transverse rectus abdominis musculocutaneous, or vertical rectus abdominis musculocutaneous flaps) underwent intraoperative stimulation of nerves innervating the infraumbilical segment of the rectus. Nerve course and extent of rectus muscle contraction were recorded.

Results: In each case, three to seven nerves entered the infraumbilical segment of the rectus abdominis. Small nerves (type 1) innervated small longitudinal strips of rectus muscle, rather than transverse strips as previously described. There was significant overlap between adjacent type 1 nerves. In 18 of 20 cases, a single large nerve (type 2) at the level of the arcuate line supplied the entire width and length of rectus muscle.

Conclusions: Nerves innervating the rectus abdominis are at risk during DIEP flap harvest. Small, type 1 nerves have overlapping innervation from adjacent nerves and may be sacrificed without functional detriment. However, large type 2 nerves at the level of the arcuate line innervate the entire width of rectus muscle without adjacent overlap and may contribute to donor-site morbidity if sacrificed.

******

Here's my take....

The long and the short of it is that for DIEP flap surgery to be considered successful several things need to happen (in my opinion):

1) the tissue (flap) transferred to the chest to create the new breast must survive. ie the new breast must live. Obvious.
2) the patient must not suffer any ill-effects from removal of the tissue ("flap") from the abdomen. This is what we call in the trade "donor-site morbidity". Abdominal bulging, hernia and significant loss of muscle strength fall in this category.
3) the patient must be happy.

Number 1 is obvious.

This article addresses number 2. Ideally, other than the scar, the patient's abdomen must recover completely from the surgery and suffer no long-term problems for the surgery to be deemed a full success.

Preserving all the patient's muscle is not enough if the nerves supplying it have all been cut. A muscle without a healthy nerve supply will lose it's tone, strength and function. If the DIEP surgeon does not take great care to identify and preserve the muscle's nerve supply, the risk of abdominal bulging will increase significantly and the muscle-preserving benefits of the procedure will essentially be lost.

The importance of choosing an experienced DIEP flap surgeon cannot be understated. I have heard of some patients (indeed some of mine too) entering the consultation with their DIEP flap surgeon having already decided they will be getting a DIEP flap and nothing else.

This can be a dangerous game to play. Here's why: in rare instances, patients may not have the appropriate anatomy for a DIEP flap. The most likely reason for this in our experience is prior abdominal surgery. Though this happens rarely in experienced hands, we do see it on occasion. Trying to "force" a DIEP flap out of a patient who does not have favorable anatomy requires more muscle dissection and can actually increase the risk of nerve damage. This can increase the risk of abdominal complications: loss of muscle tone, decreased muscle strength long term and abdominal bulging. In these situations,  some patients may be better served by a muscle-sparing type 2 free TRAM flap which removes a very small, postage-stamp sized piece of muscle but still preserves overall muscle function.

As long as you have chosen an experienced microsurgeon specializing in these procedures, chances are extremely high you will indeed get a DIEP flap. However, your anatomy and previous history are the deciding factors. Your surgeon didn't give that to you, he just has to work with it.

Plastic Surgeon using New Technology in Breast Reconstruction Surgery

Wendy Rigby- KENS 5 Eyewitness News

San Antonio's Methodist Hospital is one of only two facilities in the country offering a new technology to help in breast reconstruction surgery — a system that gives doctors a more precise way to see what they are operating on.

Plastic surgeon, Dr. Minas Chrysopoulo is a man on a mission. He wants more breast cancer patients to know that when they face a mastectomy, they can have their breast reconstructed at the same time. Dr. Chrysopoulo performs the new procedure at the Methodist Hospital.

It's a specialized form of breast reconstruction surgery called the "DIEP flap", where doctors take skin and fat from the patient's abdomen, and use it to form a natural-looking breast by using Novadaq's new imaging system called "SPY…" the doctor is able to preserve stomach muscles, while transferring skin and fat. The key is a special dye — a fluorescent agent injected into the body during the four hour operation.

"It's a bit like an angiogram but without exposing the patient to radiation," said Dr. Chrysopoulo. "The dye travels through the bloodstream and basically lights up the blood vessels. It provides a bit of a road map for us, and it helps us identify these vessels a little bit quicker. It helps us formulate the best surgical plan so that we can preserve the patient's abdominal muscle."

Dr. Chrysopoulo and his partners have used the SPY system on about 150 patients since February with great success. After time, the resulting breast is natural looking, and for the patient, a natural feeling.

While the abdomen is scarred like after a tummy tuck procedure, the abdominal muscles and core strength can be preserved. This tedious microsurgery is on the cutting edge of breast reconstruction. Doctors say waking up from cancer surgery with a new breast can make a big difference on a woman's outlook.

"Psycho-socially, it's a huge deal to wake up without a flat chest," Dr. Chrysopoulo said.

Only about 40 plastic surgeons in the country are using this particular procedure routinely. Patients come to San Antonio from all over the United States and even from some foreign countries to have the operation that promises less pain, a shorter hospital stay and a faster recovery.

Dr Chrysopoulo and his partners are breast reconstruction specialists and perform hundreds of DIEP flaps every year. Learn more about DIEP flap breast reconstruction surgery here.
