Abstract

Summary: Background: The thigh region is a well-known area for harvesting cutaneous flaps for microsurgery replacement, given the characteristics of the skin: thin, flexible, and glabrous. We investigated the vascular pattern of 32 cadaveric anteroproximal thighs for the possibility of an extended harvesting area, which we call the proximal femoral artery perforator region. Materials and methods: We injected colored, radio opaque latex in the external iliac artery and investigated the perforator branches from the superficial circumflex iliac, femoral common, superficial, and deep femoral (profunda femoris) arteries to the skin of the proximal femoral artery perforator region . This region was divided into 3 equal subregions (superior, medial, and lateral), and their perforators were counted and measured. Results: There was no significant difference in the number of arterial pedicles across the three subregions: 30 superior, 35 inferolateral, and 27 inferomedial. The perforators had a cutaneous path in 81% of the cases, while 6% were musculocutaneous and 5% septocutaneous, without a significant difference in their proportion in the three subregions. The mean length and diameter of the pedicles were 5.39 ± 2.1 cm and 1.07 ± 0.4 mm, respectively, without significant differences in the three subregions. Conclusions: The proximal femoral artery perforator region is a suitable area to generate flaps of various sizes and shapes, as needed by the surgeon. All perforators were constant and possessed a sufficient diameter and length for a successful anastomosis during the surgical procedure. The donor site retains all technical advantages to successfully replace areas of glabrous skin.
