The abdominal wall is particularly advantageous as a donor site due to the reliability of its vascular supply. Although the cutaneous perforators of the deep inferior epigastric artery (DIEA) and the superficial inferior epigastric artery (SIEA) may show significant individual variability, the DIEA itself has been shown to be ever-present as a vascular pedicle and to be highly dependable. The increasing use of preoperative computed tomographic angiography (CTA) has led to increasing reports of anatomic variability. With the use of preoperative CTA, we describe a unique case of a completely absent DIEA in patient who had not previously undergone any open abdominal surgery. The absence of the DIEA had led to vascular changes throughout the abdominal wall, including dilatation of both SIEAs and the ipsilateral deep superior epigastric artery. Preoperative CTA in this setting helped us identify this anomaly and aided surgical planning. The incidence of this anomaly was subsequently reviewed in 150 consecutive CTA scans performed at our institution.
