目的探讨采用桡动脉掌浅支(superficial palmar branch of the radial artery,SPBRA)腕横纹部flow-through皮瓣修复伴动脉缺损的拇指创面方法及疗效。方法 2012年2月-2013年11月,收治8例伴双侧动脉缺损的拇指软组织缺损患者。男5例,女3例;年龄19~51岁,平均30.5岁。致伤原因:挤压伤4例,撕脱伤3例,绞勒伤1例。致伤部位:掌指关节3例,近节掌侧2例,指间关节掌侧3例。软组织缺损范围3.5 cm×1.5 cm^6.5 cm×2.0 cm。指动脉缺损2.5~8.5 cm,平均5.3 cm。受伤距手术时间2.0~4.5 h,平均3.2 h。采用SPBRA腕横纹岛状皮瓣逆行移位修复,皮瓣切取范围4.0 cm×2.0 cm^7.5 cm×3.0 cm。供区直接缝合。结果除1例因血管变异改变术式外,其余均顺利完成手术。术后皮瓣均完全成活,创面Ⅰ期愈合;供区切口均Ⅰ期愈合。患者均获随访,随访时间6~18个月,平均13个月。皮瓣颜色及质地与周围正常皮肤相似,供区无明显瘢痕,腕部功能正常。末次随访时,患指功能按中华医学会手外科学会上肢部分功能评定试用标准评定:获优6例,良1例,中1例,优良率87.5%。结论 SPBRA腕横纹部flow-through皮瓣修复伴动脉缺损的拇指软组织缺损,具有手术操作简便、血运可靠、术后手部功能及外观恢复好的优点。
Objective To investigate the effectiveness of the island flaps based on the superficial palmar branch of the radial artery（SPBRA） to repair the thumb wound. Methods Between February 2012 and November 2013, 8 cases of thumb defects and bilateral artery defect were treated. There were 5 males and 3 females with an average age of 30.5 years（range, 19-51 years）. The injury was caused by crush（4 cases）, avulsion（3 cases）, and twist（1 case）. The injury located at the metacarpophalangeal joints in 3 cases, at the proximal palmar side in 2 cases, and at the interphalangeal joints in 3 cases. The defect size ranged from 3.5 cm×1.5 cm to 6.5 cm×2.0 cm. The digital artery defect was 2.5-8.5 cm（mean, 5.3 cm）. The disease duration was 2.0-4.5 hours（mean, 3.2 hours）. The reversed island flaps based on the SPBRA were designed, which size was 4.0 cm×2.0 cm to 7.5 cm×3.0 cm. The donor sites were closed directly. Results The operation was successfully completed in 7 patients except 1 patient having vascular variation. All flaps survived completely. Wound and incision at the donor site healed by first intention. All patients were followed up 6-18 months（mean, 13 months）. The flaps had similar color and texture to adjacent skin. Linear scar was seen at the donor site in 1 patient, with no functional limitation. According to the functional assessment criteria of upper limb by the Hand Surgery Branch of Chinese Medical Association, the results were excellent in 6 cases, good in 1 case, and fair in 1 case, with an excellent and good rate of 87.5%. Conclusion The reversed island flap based on the SPBRA is an ideal flap for the thumb reconstruction because the advantages of reliable blood supply, easy dissection, less injury at donor site, and good repair results.
