摘要目的:探讨显微削薄腓动脉穿支皮瓣修复手指背侧软组织缺损的临床效果。方法:自2015年8月-2020年7月,深圳市中西医结合医院骨伤科收治手指背侧软组织缺损采用显微削薄腓动脉穿支皮瓣修复的患者19例,创面缺损面积为3.8 cm×1.5 cm~5.8 cm×3.0 cm,均伴指骨、肌腱外露。皮瓣切取面积4.0 cm×1.8 cm~6.0 cm×3.3 cm。根据手指背侧软组织缺损面积大小,以腓动脉穿支为中心设计皮瓣,皮瓣长、宽均比缺损创面大0.2~0.3 cm,皮瓣在深筋膜浅层切取,切取穿支血管长2.0~3.0 cm。在显微镜下将皮瓣大部分脂肪组织剔除,保护好脂肪组织间微小动脉。将皮瓣覆盖手指缺损创面,皮瓣穿支动脉与受区指掌侧固有动脉吻合,穿支动脉的伴行静脉与受区指背静脉吻合,皮瓣内的皮神经和指背神经缝接,皮瓣供区直接拉拢间断缝合。术后定期门诊及微信随访伤口愈合情况、皮瓣成活情况、皮瓣感觉及皮瓣供区恢复情况及手指的屈、伸功能等。手功能恢复按中华医学会手外科学会上肢部分功能评定试用标准评价。结果:全部伤口一期愈合,19例皮瓣全部成活。术后随访9~25个月,平均11.5个月,皮瓣外观满意,质地良好,皮瓣感觉恢复到S 4 4例,S 3 9例,S 2 6例,皮瓣供区仅留线状瘢痕；手功能恢复评价参照中华医学会手外科学会上肢部分功能评定试用标准进行,结果优18例、良1例。 结论:显微削薄腓动脉穿支皮瓣修复手指背侧软组织缺损外形良好,手术操作简单,避免了二期修薄整形手术,治疗效果好,是一种较为理想的手术方法。

abstractsObjective:To investigate the clinical effect of microdissected peroneal artery perforator flap in repair of soft tissue defect of dorsal side of the fingers.Methods:From August 2015 to July 2020, 19 patients with soft tissue defects on dorsal fingers were treated with microdissected peroneal artery perforator flap. The area of wound defect was 3.8 cm×1.5 cm-5.8 cm×3.0 cm, with exposure of phalanges and tendons. The size of flaps was 4.0 cm×1.8 cm-6.0 cm×3.3 cm. According to the size of soft tissue defects on the dorsal side of the fingers, the flaps were designed with the perforating branch of peroneal artery in the centre. The length and width of a flap were 0.2-0.3 cm bigger and wider than the area of defect. The perforator vessels with a length of 2.0-3.0 cm were arvested in the superficial layer of deep fascia. Most of the adipose tissues of the flap were removed under microscope, and the small arteries between adipose tissues were protected. The flaps were used to cover the defects of fingers. The perforator artery of the flap was anastomosed with the proper palmar digital artery of the recipient site, the accompanying vein of the perforator artery was anastomosed with the dorsal digital vein of the recipient site, and the cutaneous nerve in the flap was anastomosed with the dorsal digital nerve. The donor sites were directly pulled together and sutured intermittently. Outpatient and WeChat follow-up were conducted after operation, including wound healing, flap survival, flap sensation, donor site recovery, and flexion and extension functions of the fingers. Functional recovery was evaluated according to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association.Results:All wounds healed in Ⅰ stage, and all 19 flaps survived. The follow-up ranged from 9 to 25 months, with an average of 11.5 months. The appearance of the flaps was satisfactory and the texture was good. Sensation recoveried to S 4 in 4 paitients, S 3 in 9 patients and S 2 in 6 patients, and with only a linear scar was left in the donor sites. The hand function recovery was evaluated according to the Trial Criteria of Upper Limb Function Evaluation of the Hand Surgery Society of the Chinese Medical Association, with 18 cases were excellent and 1 was good. Conclusion:The microdissected peroneal artery perforator flap is an ideal surgical method to repair the soft tissue defect of dorsal side of the fingers, which has good shape and simple operation, avoids the secondary thinning and plastic surgery and offers good therapeutic effects.
