The anatomy of perforator for anteromedial thigh (AMT) flap is a very much-debated issue. In this article, we report AMT perforator vascular anatomy by CT-Angiography (CTA) evaluation of 68 consecutive healthy thighs. Perforators emergence, caliber, length, course, and source vessel in the central three fifth of the thigh were studied by a virtual coordinate system. A mean 4.94 ± 1.75 perforators per thigh (average length, 2.6 ± 0.99 cm) from superficial femoral artery (SFA) were found, emerging medial and lateral to sartorius muscle. A mean 0.4 ± 0.74 perforators per thigh (average length, 2.45 ± 0.97 cm) branched from rectus femoris artery, of which 80% were emerging lateral to sartorius muscle. A mean 0.62 ± 0.91 perforators per thigh (average length, 3.1 ± 1.23 cm) branched from an unnamed branch of SFA, of which 88% were emerging lateral to the sartorius muscle. Perforators' calibre was inferior to 1-5 mm in 177 perforators (51.6%), between 1.5 and 2 mm in 159 (46.7%), and over 2 mm in 7 (2%). The findings from this study show that AMT region is plenty of reliable perforators with overlapping fascial emergence but branching from three different source arteries. © 2014 Wiley Periodicals, Inc.
