股后内侧区游离股深动脉穿支皮瓣修复四肢创面

Repair of limb wounds with free profunda artery perforator flap in posteromedial femoral region

目的探讨应用股后内侧区游离股深动脉穿支皮瓣(profunda artery perforator flap,PAPF)修复外伤性肢体皮肤缺损的疗效。方法 2015年3月—2017年4月,采用股后内侧区游离PAPF修复外伤性肢体皮肤缺损伴深部组织外露11例。男7例,女4例;年龄26～54岁,平均39岁。手、前臂皮肤缺损4例,小腿、足部皮肤缺损7例。致伤原因:交通事故伤6例,机器挤压伤3例,压砸伤2例。创面范围11 cm×7 cm～18 cm×11 cm。受伤入院至皮瓣修复时间4～9 d,平均7.3 d。术中游离PAPF切取范围为15 cm×9 cm～22 cm×13 cm;8例供区一期闭合,3例无法直接闭合采用植皮覆盖创面。结果术中皮瓣切取时间为40～90 min,平均47 min。术后所有皮瓣及植皮区均顺利成活,创面Ⅰ期愈合。11例患者均获随访,随访时间6～19个月,平均12个月。皮瓣质地柔软,颜色与伤肢周围皮肤相似,无明显色素沉着及毛发生成。其中3例患者进行了二期皮瓣修薄。末次随访时所有患者伤肢功能恢复良好。皮瓣供区可见纵形瘢痕,位置隐蔽;所有患者随访过程中均未诉皮瓣供区瘢痕影响性生活。结论股后内侧区游离PAPF具有穿支恒定、术式简便、供区隐蔽的优点,修复四肢皮肤缺损创面能取得满意疗效。

Objective To explore the effectiveness of free profounda artery perforator flap(PAPF) in the posteromedial femoral region for the treatment of traumatic skin defects of limbs. Methods Between March 2015 and April 2017, 11 cases of traumatic limb skin defect with deep tissue exposure were treated with free PAPF in posteromedial femoral region. There were 7 males and 4 females, with an average age of 39 years(range, 26-54 years). There were 4 cases of upper limb skin defect and 7 cases of lower limb skin defect. The causes of injury included 6 cases of traffic accident injury, 3 cases of machine crush injury, and 2 cases of crush injury. The size of wounds ranged from 11 cm×7 cm to18 cm×11 cm. The time from post-traumatic admission to flap repair were 4-9 days(mean, 7.3 days). The size of free PAPF ranged from 15 cm×9 cm to 22 cm×13 cm. The donor site of 8 cases were closed directly;3 cases could not be closed directly, and skin grafting was used to cover the wound. Results The time of skin flap harvest was 40-90 minutes(mean,47 minutes). All flaps and skin grafts survived and the wounds healed by first intention. All the 11 patients were followed up 6-19 months(mean, 12 months). The skin flaps were soft in texture, similar in color to the skin around the injured limbs, without obvious pigmentation and hair overgrowth. Three of them underwent second-stage skin flap thinning. At last follow-up, the limb function of all patients recovered well. Longitudinal scar could be seen in the donor site of the flap,and the location was concealed. All patients did not complain that scar of the donor site affected their sexual life during the follow-up. Conclusion Free PAPF can achieve satisfactory results in repairing skin defects of extremities. The flaps have the advantages including constant perforator branches, simple operation, and concealed donor site.
