Profunda femoris artery perforator flaps: a detailed anatomical study

Abstract

The thigh region has many perforators when compared to the other areas in the body. Surgeons have disregarded the posterior thigh region as a potential donor site for perforator flap surgeries, presumably owing to the positioning difficulties of the patients during the intervention and inadequate anatomical information. The purpose of this study was to provide comprehensive data concerning the profunda femoris artery. Perforator flaps on an anatomical basis, and to describe anatomical landmarks, easing topographical flap dissection in various combinations. Eleven fresh cadaver thighs were obtained from different individuals using the Willed Body Program. The mean age was 43.5 years (29–63), and the male/female ratio was 7/4. We evaluated each cutaneous perforator for localization, diameter, source artery, numbers, length, and type (musculocutaneous or septocutaneous).We observed at least two perforators in all thighs in the study. Medial perforators consisted of 74.5% musculocutaneous and 25.5% septocutaneous perforators. Lateral perforators consisted of 68.3% septocutaneous perforators and 31.7% musculocutaneous perforators. Positioning difficulties of the patient during surgery and inadequate anatomical information cause surgeons to avoid this area. However, surgeons may easily perform these flaps in reconstructive surgery as a local or free flap with substantial success.
