P191. Incidental findings in 1000 consecutive CT angiograms for DIEP flap breast reconstruction

Abstract

Introduction: CT angiography is the core of pre-operative assessment for patients undergoing free Deep Inferior Epigastric Perforator (DIEP) flap breast reconstruction. Knowing the vascular anatomy of the flap has been proven to help preoperative decision making and reduce operating time. Incidental findings are not uncommon with literature quoting frequencies between 13% and 64%. As these findings can require further investigations and potentially delay surgery, the purpose of this study was to clarify the rate, nature of these findings and how this should be communicated to the patients.
