Abstract

  Flaps are necessary, when important structures such as bone, tendon, nerve and vessel are exposed. Arterialized venous free flap is suited to the coverage of finger and hand because the thickness of venous flap is thin. Authors performed 65 cases arterialized venous free flap for the soft tissue reconstruction of the hand and finger. The size of donor defect were from 1×1 cm to 7 ×12 cm. The mean flap area was 9.1 cm2. The recipient sites were finger tip in 34 cases, finger shaft in 29 cases and hand in 2 cases. The donor sites were volar aspect of distal forearm in 40 cases, thenar area in 17 cases and foot dorsum in 6 cases. The types of arterialized venous free flap were A-A type in 4 cases and A-V type in 61 cases. The length of afferent vein was from 0.5 cm to 3 cm (mean 1.7 cm) and efferent vein was from 1 cm to 10 cm (mean 2.2 cm). 58 flaps(89.2%) survived eventually. 42 flaps(64.6%) survived totally without any complication. 8 flaps(12.3%) showed the partial necrosis but they were healed without any additional operations. 8 flaps (12.3%) showed the partial necrosis requiring the additional skin graft. We had a satisfactory result by using arterialized venous free flap for the soft tissue reconstruction of finger and hand. We believe that volar aspect of distal forearm, thenar area, foot dorsum are suited as a donor site and the short length of the flap pedicle, the strong arterail inflow affect the survival rate of arterialized venous free flaps.
