Deep Circumflex Iliac Artery (DCIA) Free Flap without DCIA: Report of a Unique Case

The iliac crest free flap is a reliable source of cancellous bone, muscle, and skin. The vascularization of this flap arises from the deep circumflex iliac artery (DCIA) which allegedly is always present. The authors report a unique case of successful microvascular transplantation of an iliac crest osteomyocutaneous free flap in a patient in whom the DCIA and DCIV were absent.
