Abstract:

Objective To produce a digitized model of the anteromedial thigh for determining the anatomical relationships of perforators in each zone of the anteromedial thigh. Methods Five fresh unfixed corpses underwent whole body red latex injection. Fifteen fresh cadavers injected with a modified lead oxide-gelatin mixture for three-dimensional reconstruction using a spiral computed tomography scanner and specialized software (Mimics). All of specimens were then dissected by layers. Angiography and photography were used to document the precise course, size, location, and type of individual perforators in the anteromedial thigh region. The surface areas of cutaneous territories and perforator zones were measured and calculated with Photoshop and Scion Image. Results The arterial supply to the integument of the anteromedial thigh was divided into proximal, middle, and distal zones. There were (21±4.0) perforators with diameters of greater than or equal to 0.5 mm; the average external diameter was (0.8±0.1) mm. Each perforator supplied an average area of (44±4.8)cm2. A number of perforators arised from the femoral artery,lateral circumflex femoral artery,and descending genicular artery in the middle zone of the anteromedial thigh. Conclusions The anteromedial thigh is an excellent donor site for local and distant flaps. Perforator flaps could be based in a variety of ways from each zone, especially the middle zone.
