带蒂胸腹轴型皮瓣早期修复上肢深度蛇伤溃疡

总结胸腹轴型皮瓣早期修复上肢不同部位的深度蛇伤溃疡的经验，评价其应用价值。本组１６例，胸脐皮瓣２例，侧胸腹皮瓣１例，髂腰皮瓣５例，下腹皮瓣６例，下腹分叶皮瓣１例，髂腰加下腹Ｙ形皮瓣１例。术后１例皮瓣远端坏死，３例轻度感染，１６例断蒂后全部成活。随访３个月～７年，皮瓣质地和弹性均好，手功能基本恢复。认为，带蒂胸腹轴型皮瓣是修复上肢深度蛇伤溃疡理想的方法。

PEDICLED THORACO ABDOMINAL SKIN FLAP APPLIED IN EARLY REPAIR OF DEEP ULCER OF UPPER EXTREMITY RESULTING FROM SNAKE BITE INJURY/

The ulcer resulting from snake bite injury was characterized by deep and wide tissue necrosis and secondary infection. The patient was at high risk of loss of function of his extremity. From 1989 to 1996, 16 cases with deep ulcer of the upper extremity resulting from snake bite injury were treated with different types of axial thoraco abdominal skin flaps, depending on the location of the ulcer. Thoraco umbilical skin flap was used in 2 cases, lateral thoraco abdominal skin flap in 1 case, iliolumbar skin flaps in 5 cases, lower abdominal skin flaps in 6 cases, lower abdominal divided foliated skin flap in 1 case and Y shaped hypogastric skin flap in 1 case. Reparative operation was carried out within 3 weeks after injury and primary repair were undertaken in 6 of them. The pedicles were divided in 17 to 24 days after operation. Twelve flaps survived. Three of the 6 flaps had mild signs of inflammation which disappeared after administration of antibiotics. One had necrosis of the distal part of the flap, and was healed with split skin graft. This type of skin flap was an ideal method for the treatment of snake bite injury of the upper extremity.
