ABSTRACT
Objective To report 11 cases with the tissue defects of their upper or lower limbs repaired with the anastomsed medial sural artery perforator flaps.Methods The free medial sural artery perforator flaps,with length of 8 cm to 15 cm and width of 6 cm to 14 cm were used for tissue defect reconstruction of the distal upper or lower limbs in 11 cases,including 6 females and 5 males.The flap was harvested from the ho- mo-lateral calf,confined between the posterior-medial edge of the tibia and the middle line of the calf and a- bove the distal half part of the medial sural muscle,with a same axis of this muscle.Results Ten cases survived very well,which was relatively thin,and the donor site can be acceptable.One case resulted in a complete flap necrotized and covered with a split skin graft.No obvious motor function defect was observed of the donor leg.Conclusion The anastomsed medial sural artery perforator flap is alternative donor flap for the upper or lower limb tissue defect repair,especially for the defect in the hand or foot.
