A CT angiogram (CTA) is a special type of CT scan that examines the blood vessels in the abdomen to determine if they are intact and able to be used for DIEP flap reconstruction. It can also provide a "road map" for the surgeon and help locate the largest blood vessels ("perforators").
While some surgeons obtain CT angiograms on their patients routinely before DIEP flap surgery, in our opinion not all patients need the study. A very good example is patients who have never had abdominal surgery. Much depends on surgeon preference and experience.
It is also important to realize that the test exposes patients to radiation; in many cases, patients have already had more than their fair share of radiation as part of their breast cancer treatment! At PRMA, we usually only recommend a pre-operative CTA in patients that have had multiple previous abdominal surgeries and there is a question about the vascular anatomy.
There is no doubt, despite the radiation exposure, a CTA can be an excellent planning tool when needed. Be sure to discuss any concerns you have regarding previous abdominal surgeries and the need for a CT angiogram with your plastic surgeon.
I hope this info helps!
