A Standardized Approach to Deep Inferior Epigastric Perforator Flap Marking

Abstract

Summary:. The deep inferior epigastric perforator (DIEP) flap is the most commonly utilized flap in autologous breast reconstruction. This perforator-based free flap includes the lower abdominal wall adipocutaneous layers while sparing the abdominal musculature. Several studies have looked at preoperative planning for DIEP flap reconstruction using CT angiography; however, no study to date has proposed a standardized approach to DIEP flap markings. We propose a novel technique to standardize DIEP flap marking that leads to greater symmetry and consistency in the donor site.
