【摘要】 目的 探讨指固有动脉背侧皮支皮瓣修复手指创面的疗效。方法 12例手指软组织缺损患者, 均采用指固有动脉背侧皮支皮瓣修复手指创面。观察患者的手术效果。结果 12例患者皮瓣全部成活, 创面一期愈合, 未见动静脉危象, 其中1例术后皮瓣远侧缘部分坏死, 经换药处理后愈合。本组患者术后随访6~12个月, 平均随访9个月, 皮瓣质地柔软, 瘢痕不明显, 外观良好;两点辨别觉为6~10 mm, 感觉恢复在S1~S3+, 伤指指间关节活动良好。结论 指动脉背侧皮支解剖恒定, 供血可靠, 其不损伤指动脉主干, 操作简单, 设计灵活, 指固有动脉背侧皮支皮瓣修复手指软组织缺损是一种理想的方法。

【Abstract】 Objective To discuss the efficacy of dorsal cutaneous branch flap of digital arteries in repairing wounds of fingers. Methods A 12 patients with soft tissue defects of the fingers were repaired by dorsal cutaneous branch flap of digital arteries. The surgical effect of patients was observed. Results All the flaps survived and the wound healed in the first stage. There was no arteriovenous crisis. The distal edge of the flap was partially necrotic in 1 case and healed after dressing change. The patients were followed up for 6-12 months, with an average of 9 months. The flap texture was soft, the scar was not obvious, and the appearance was good; the two-point discrimination was 6-10 mm, the sensory recovery was in S1-S3+, and the injured fingers and joints moved well. Conclusion The dorsal cutaneous branch of digital arteries has the advantages of constant anatomy, reliable blood supply, no damage to the main finger artery, simple operation and flexible design. It is an ideal method to repair the soft tissue defect of fingers with the dorsal cutaneous branch flap of digital arteries.

手指軟组织缺损是临床上的常见外伤, 多由机器切割、重物压砸、烧烫伤等造成, 伤指常伴有肌腱、神经、骨质的外露并缺损, 传统的修复方法主要包括邻指皮瓣、指动脉逆行岛状皮瓣、鱼际皮瓣等[1-5]。随着显微解剖学的发展与皮穿支皮瓣技术的进步, 近年来皮穿支皮瓣在修复四肢软组织缺损中应用广泛。2016年6月~2017年9月, 本科应用手指固有动脉背侧皮支皮瓣移植修复手指软组织缺损12例, 获得满意的疗效。现报告如下。
