In plastic surgery, flap reconstruction has been utilised to repair defects in every part of the body, in an effort to restore form and function to patients. The basis of every flap is its blood supply, therefore this series of studies investigates the vascular territory of named arteries, veins and even perforators, utilizing computer tomography (CT) and TeraRecon software. The latter two is technology which allows appreciation of vascular flow in 3D and 4D (dynamic studies), whereas previous studies of vascularity has only been static and in 2D. Vascular anatomy studies were performed using fresh cadavers. Perforator flaps on the anterior trunk studied were the internal mammary artery perforator (IMAP) flap, the transverse rectus abdominis musculocutaneous (TRAM) flap, the deep inferior epigastric artery perforator (DIEP) flap and the superficial inferior epigastric artery (SIEA) flap. Posterior trunk flaps included the posterior intercostal artery perforator flap, the lumbar artery perforator flap and the superior gluteal artery perforator (SGAP) flap. In the upper extremity, we studied the supraclavicular artery perforator flap. In the lower extremity, we studied the gracilis musculocutaneous flap. Trends and characteristics are noted in the vascular analyses, and four major principles drawn are discussed in the last chapter.
