Blood supply and innervation of the supermedial thigh flap employed in one-stage reconstruction of the scrotum and vulva--an anatomical study.
The supermedial thigh flap is an arterial and sensate flap. Anatomical studies reveal both large and small nutrient arteries. Its largest and most consistent artery is the superficial branch of the deep external pudendal artery, which constitutes the main circulation. The secondary blood supply to the base of the flaps is contributed by musculocutaneous perforators of the medial circumflex femoral artery. Subcutaneous branches of the superficial femoral artery, when present, are an additional source of arterial supply. Branches of the ilioinguinal nerve provide sensory innervation to the flaps.
