Microsurgical Engineering: Bilateral Deep Inferior Epigastric Artery Perforator Flap with Flow-Through Intraflap Anastomosis

Abstract

Squamous cell carcinoma (SCC) of the head and neck affects a significant number of people around the world every year. Treatment generally entails surgical resection, radiotherapy, chemotherapy, or some combination of the three. Following resection, microsurgical reconstruction can provide definitive coverage, replace many tissue types simultaneously, and bring healthy tissue to irradiated wound beds. Microsurgical engineering, the manipulation and reorganization of native vascular tissue, can further augment the adaptability of free tissue transfer to complex, compromised wound beds. We present one such case. The patient described in the following report was treated for a recurrent SCC of the left face, which required extensive resection resulting in a complex, composite tissue defect with compromised vascular supply. Using the principals of microsurgical engineering, definitive coverage of the defect, with accept- able aesthetic result, was achieved via bipedicle, DIEP flap with flow-through intraflap anastomosis.
