Management of abnormal deep inferior epigastric vessels in microsurgical breast reconstruction: a report of 3 complex cases

Abstract

The deep inferior epigastric artery perforator flap is the gold standard in microsurgical breast reconstruction. It is now increasingly offered in patients with previous abdominal scars and in such cases, computed tomography angiography (CTA) is routinely implemented. However, previous injury of the deep inferior epigastric vessels may be difficult to detect with CTA. We report three cases of successful bilateral breast reconstruction, in which a unilateral DIEA was found to be abnormal. In the first two cases, the unilateral DIE vessels were found to be damaged and the flaps salvaged based on the deep superior epigastric artery. In the third patient, previous DIEA injury resulted in vessel recanalization, which was only evident following initial anastomotic failure. In this case, the damaged DIEA segment was subsequently removed and the flap successfully revascularized. All three patients had an uneventful post-operative recovery and all flaps survived with no complications. Based on our experience, we believe that awareness of the potential pitfalls and careful planning for lifeboats are essential to avoid flap loss in such circumstances.
