Background: Abdominal donor site flaps are the standard for autologus breast reconstruction. In this study we evaluated the effects of a preoperative abdominal wall computed tomographic angiography in women who had undergone delayed unilateral breast reconstruction with abdominal perforator flaps.

Methods: Between October 2007 and June 2008, 24 women were admitted in Henri Mondor General Hospital, Creteil, France for breast reconstruction. The perforator vessel was chosen preoperatively (based on scanner data), located and dissected directly.

Results: We found an absolute correlation between the radiological information and intraoperative findings. An average of one hour was saved in delayed unilateral breast reconstruction with deep inferior epigastric artery perforator flap.

Conclusion: We concluded that CT angiography (CTA) provides valuable preoperative information enabling identification of the most suitable perforator in view of its calibre, location, course, and anatomic relationships. Once located, we can proceed directly to its dissection during surgery, making it a faster and safer technique.
