Abstract
INTRODUCTION: The superficial circumflex iliac artery perforator flap (SCIP) has gained widespread popularity as local or free flap to cover soft tissue defects. However, there are numerous anatomical variations in terms of size, location and reliability of its perforators This cadaveric study aimed to focus on the anatomical bases of this flap. MATERIALS AND METHODS: A bilateral dissection of seven cadavers was performed to harvest 14 flaps. Superficial circumflex iliac artery parameters, number, length and diameters of perforators were measured. Correspondent perforasomes were highlighted through semi-selective injections. RESULTS: The major perforator of the superficial branch had a mean caliber of 2.0 mm, and a mean length of 1.8 mm. The major perforator of the deep branch had a mean caliber of 2.1 mm and a mean length of 1.43 mm. The mean area of the superficial pattern perforasome was 178.6 cm2 and the mean measured surface of the deep pattern perforasome was 156.2 cm2. The descending branches of the deep branch anastomosing with the ascending branch of the lateral circumflex femoral artery were found in three cases. CONCLUSION: Several anatomical variations were observed in this anatomical study, but major perforators supplying large perforasomes were always found.
