摘要:
目的 探讨采用修薄的股前外侧穿支皮瓣联合分指及指蹼成形术序贯治疗全手脱套毁损性创面的效果。 方法 该研究为回顾性观察性研究。2012年1月—2023年1月,宁波市第六医院收治15例符合入选标准的全手脱套毁损性创面患者,其中男10例、女5例,年龄17~75岁,创面均合并骨骼或肌腱外露。Ⅰ期皮瓣移植术前均急诊行清创+负压封闭引流处理,彻底清创后,创面面积为11.0 cm×3.0 cm~23.0 cm×13.5 cm。设计并切取一侧或双侧股前外侧穿支皮瓣（面积为12.5 cm×5.0 cm~25.0 cm×15.5 cm）,并对皮瓣进行修薄处理后修复手部皮肤软组织缺损。将供区创面直接缝合或取对侧大腿中厚皮片移植修复。根据需要,于Ⅰ期术后每隔约3个月行1次或多次分指+指蹼成形术,对皮瓣进行整复。Ⅰ期术后,观察皮瓣成活、并发症发生情况,供区创面愈合情况。随访时,观测皮瓣外观、两点辨别觉距离及手部功能等情况。末次随访时,根据中华医学会手外科学会上肢部分功能评定试用标准对患手功能进行评定。 结果 Ⅰ期术后,15例患者皮瓣均完全成活,其中1例患者皮瓣出现动脉危象,经探查并重新吻合血管后完全成活；供区创面全部愈合。Ⅰ期术后随访6~18个月,皮瓣外形稍臃肿,有少许色素沉着,两点辨别觉距离为8~11 mm；手指可完成屈、伸、捏、握等基本生活动作。末次随访时,患手功能评定为优者3例、良者9例、可者3例。 结论 针对全手脱套毁损性创面,Ⅰ期采用游离移植一侧或双侧修薄的股前外侧穿支皮瓣进行修复,后期采用分指+指蹼成形术对皮瓣进行整复,可基本恢复患手生活所需的捏握功能,值得临床推广。 Abstract:Objective To investigate the effects of thinned anterolateral thigh perforator flaps combined with finger splitting and webplasty in sequential treatment of degloving destructive wound of total hand. Methods This study was a retrospective observational study. From January 2012 to January 2023, a total of 15 cases who met the inclusion criteria with degloving destructive wound of total hand were admitted to Ningbo No.6 Hospital, including 10 males and 5 females, aged 17-75 years. The wounds were all combined with exposed bones or tendon. Emergency debridement and vacuum sealing drainage were performed in all cases before flap transplantation in stage Ⅰ. After thorough debridement, the wound area was 11.0 cm×3.0 cm-23.0 cm×13.5 cm. One or both anterolateral thigh perforator flaps with size of 12.5 cm×5.0 cm-25.0 cm×15.5 cm were designed, cut, and thinned to repair the skin and soft tissue defects of the hand. The donor site was sutured directly or repaired with medium-thickness skin graft from the opposite thigh. As needed, the flap was reconstructed by finger splitting and webplasty once or more times every 3 months after stage Ⅰoperation. The survival and complications of flap and wound healing at the donor site were observed after stage Ⅰoperation. The appearance of flap, two-point discrimination distance, and hand function were observed during the follow-up. At the final follow-up, the function of the affected hand was evaluated by the trial standards for evaluation of partial function of upper extremity by the Hand Surgery Society of Chinese Medical Association. Results After the operation of stage Ⅰ, all the flaps of 15 cases of patients survived completely, including 1 case that had arterial crisis of flap but survived completely after exploration and re-anastomosis of blood vessels; all the wounds at the donor site healed. During the follow-up period of 6 to 18 months after stage Ⅰ, the flap was slightly swollen, with a little pigmentation, and the two-point discrimination distance in the finger flap was 8-11 mm. The fingers could complete the basic life actions such as flexion, extension, pinch, and grip. At the final follow-up, 3 cases were excellent, 9 cases were good, and 3 cases were acceptable in function evaluation of the affected hand. Conclusions For degloving destructive wound of total hand, free transplantation of one or both thinned anterolateral thigh perforator flaps is used for repair in stage Ⅰ, and finger splitting and webplasty are used to reconstruct the flaps in the later stage, which can basically restore the pinch and grip function of the affected hand that is required for daily life, and is worthy of clinical promotion. -
