游离桡动脉掌浅支皮瓣修复手指软组织缺损

Application of free superficial palmar branch of radial artery flap in repairing of soft tissue defect of fingers

目的探讨游离桡动脉掌浅支皮瓣修复手指软组织缺损的疗效。方法 2014年6月—2017年6月,采用游离桡动脉掌浅支皮瓣修复10例(10指)手指软组织缺损。男8例,女2例;年龄23～42岁,平均29.8岁。致伤原因:电锯切割伤6例,机器挤压伤2例,玻璃划伤2例。受伤至入院时间为1～8 h,平均3 h。损伤部位:示指中节掌侧3例,示指末节掌侧1例,中指末节掌侧3例,环指远指间关节尺侧1例,小指末节掌侧2例。皮肤软组织缺损范围为1.8 cm×0.9 cm～2.8 cm×2.1 cm。皮瓣切取面积为2.0 cm×1.0 cm～3.0 cm×2.3 cm。供区均直接缝合。结果术后皮瓣顺利成活,创面均Ⅰ期愈合;供区切口均Ⅰ期愈合。患者均获随访,随访时间6～12个月,平均9个月。皮瓣质地优良,外形满意,痛觉、温觉、触觉均恢复较好;末次随访时皮瓣两点辨别觉为6～13 mm,平均7.5 mm。末次随访时,按中华医学会手外科学会手功能评定试用标准评定:优8例,良2例。腕部供区仅遗留线性瘢痕。结论游离桡动脉掌浅支皮瓣供区隐蔽、创伤小,皮瓣切取简便、吻合容易,是修复手指软组织缺损的一种良好方法。

Objective To evaluate the surgical technique and the effectiveness of the free superficial palmar branch of the radial artery flap to repair soft tissue defect of fingers. Methods Between June 2014 and June 2017, 10 cases（10 fingers） of soft tissue defects of fingers were repaired with the free superficial palmar branch of the radial artery flaps.There were 8 males and 2 females with an average age of 29.8 years（range, 23-42 years）. The causes of injury included the chainsaw cutting injury in 6 cases, the machine crush injury in 2 cases, and the glass scratching in 2 cases. The time from injury to admission was 1-8 hours with an average of 3 hours. The locations were the volar of the middle of index finger in 3 cases, the volar of the distal of index finger in 1 case, the volar of the distal of middle finger in 3 cases, the ulnar side of distal interphalangeal joint of ring finger in 1 case, and the volar of the distal of the little finger in 2 cases. The area of soft tissue defect ranged from 1.8 cm×0.9 cm to 2.8 cm×2.1 cm, and the area of flap ranged from 2.0 cm×1.0 cm to 3.0 cm×2.3 cm. The donor sites were sutured directly. Results All flaps survived after operation, and the wounds healed by first intention. The incisions of donor site also healed by first intention with a linear scar. All cases were followed up 6-12 months（mean, 9 months）. The appearance and texture of the flaps were satisfactory. The pain sensation, warm sensation, and touch sensation of the flap recovered. At last follow-up, the two-point discrimination of the flap was 6-13 mm（mean, 7.5 mm）. According to the assessment of the upper limb function issued by tha Hand Surgery Society of Chinese Medical Association, the results were graded as excellent in 8 cases and good in 2 cases. Conclusion The free superficial palmar branch of the radial artery flap is easy to harvest and anastomose and has small injury. It is an ideal method in repairing of soft tissue defects of fingers.
