title: Great toe-to-hand transfer: role of the preoperative lateral arteriogram of foot.
abstract: This report correlates the results of the lateral angiogram of the foot with the operative dissection and eventual outcome in 29 patients in whom a great toe-to-hand transfer was performed to treat a traumatic loss of the thumb. Our angiographic findings were confirmed by surgical exploration and indicated that (1) in 20 (70%) of 29 patients the first dorsal metatarsal artery (FDMA) originated from the dorsalis pedis artery, dorsal to the midlongitudinal axis of the first metatarsal bone; (2) in 6 (20%) of 29 patients the FDMA originated from the dorsalis pedis artery, plantar to the midlongitudinal axis of the first metatarsal bone; (3) in the remaining 3 (10%) of 29 patients the arteriogram of the lateral foot indicated that the plantar metatarsal artery supplied the great toe in a dominant pattern, necessitating its use as the donor vessel; and (4) the measured lumenal diameters of the dorsal and plantar metatarsal arteries (mean diameter = 1.30 mm and 1.27 mm, respectively) did not significantly differ. The lateral views of the foot were helpful in permitting distinct identification of the location and size of the metatarsal arteries to the great toe.
