Abstract:

Objective　To investigate the application and clinical effects of flow-through anterolateral thigh perforator flap for the treatment of skin and soft tissue defects of palm with circulatory disorder.  Methods　Anterolateral thigh perforator flap was used to repair skin and soft tissue defects of palm with arterial circulatory disorder in 9 cases. The injured artery was bridged by descending branch of lateral circumflex femoral artery for blood supply reestablishment. The flap was designed based on the perforating artery of lateral circumflex femoral artery (intermuscular branch or cutaneous branch). The length of descending branch of lateral circumflex femoral artery was from 4cm to 8cm, and the area of the flap was from 7 cm×9 cm to 11 cm×16 cm.　Results　All flaps and skin grafts of donor sites survived, and the repaired hands had good blood supply.  All patients were followed up for 6 to 9 months．The flap and hand tip both had good blood supply.  Protective sensation of the flap as well as sweating function was recovered. Scar formation occurred in some donor sites.　Conclusion　It may be an ideal method to use flow-through anterolateral thigh perforator flap for the treatment of skin and soft tissue defects of palm with arterial circulatory disorder.  It can bridge the vessel and cover the wound.
