Abstract

The deep inferior epigastric artery (DIEA) is a reliable pedicle in the design of DIEA perforator flaps, with variations in its anatomy infrequent. Previous studies describing its branching pattern have all been based on cadaveric anatomy and described the following three branching patterns: Type 1 (single trunk), Type 2 (bifurcating trunk), and Type 3 (trifurcating trunk). The increased use of preoperative imaging, particularly with computed tomographic angiography (CTA), has enabled visualization of the DIEA and its branches in vivo, providing a functional view of this anatomy. We undertook a study of 250 patients (500 hemiabdominal walls) undergoing preoperative CTA before DIEA perforator..
