ABSTRACT
Autologous breast reconstruction using abdominally based perforator flaps has become increasingly popular following mastectomy for breast cancer. Of these, the deep inferior epigastric artery perforator (DIEP) flap represents one of the most popular techniques. However, surgeons must remain cognizant of anatomic variations in the abdominal wall vasculature that could complicate or preclude planned DIEP flaps. In this case, a 64-year-old female with a history of prior tubal ligations and caesarean sections underwent preoperative computed tomographic angiography (CTA) for planned autologous breast reconstruction with a DIEP flap. CTA revealed complete absence of the left deep inferior epigastric artery, with a sizeable left abdominal wall perforator visualized receiving retrograde flow from a crossing midline branch originating from the contralateral right deep inferior epigastric system. This vessel traversed the midline in a superficial plane in the subcutaneous tissue. Despite this aberrant anatomy, the surgical team successfully raised a unilateral DIEP flap based on the right pedicle. This case represents a unique anatomical variation of the abdominal wall and emphasises the importance of preoperative imaging when planning abdominally based free flaps.
