胸背动脉穿支皮瓣修复烧伤后严重手背瘢痕挛缩畸形

Clinical application of thoracodorsal artery perforator flap in repair of serious scar contracture of opisthenar

目的探讨应用胸背动脉穿支皮瓣游离移植修复烧伤后手背严重瘢痕挛缩的疗效。方法 2015年3月-2017年6月,收治7例手背烧伤后继发严重瘢痕挛缩畸形患者。其中男5例,女2例;年龄1148岁,平均31岁。受伤至手术时间867个月,平均42个月。手术瘢痕松解及关节复位后,遗留皮肤软组织缺损范围为5 cm×4 cm10 cm×8 cm。采用胸背动脉穿支皮瓣游离移植修复,皮瓣切取范围为5.5 cm×5.0 cm10.5 cm×9.0 cm。结果术后皮瓣全部成活,供受区切口均Ⅰ期愈合。3例患者皮瓣较臃肿,术后3个月行二期皮瓣修薄术。7例患者均获随访,随访时间632个月,平均15个月。皮瓣质地柔软,弹性好。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,皮瓣感觉S3+2例,S3 1例,S2 3例,S1 1例;手功能获优2例,良4例,可1例。随访期间肩关节活动无明显影响。结论胸背动脉穿支皮瓣游离移植修复手背严重瘢痕挛缩是一种较好的方法。

Objective To investigate the feasibility and effectiveness of thoracodorsal artery perforator(TDAP flap for repairing serious scar contracture of the opisthenar. Methods Between March 2015 and June 2017, 7 cases of serious scar contracture of opisthenar were repaired with TDAP flaps. There were 5 males and 2 females with an average age of 31 years(range, 11-48 years). The time from injury to operation was 8-67 months, with an average of 42 months.After the relocation of the joint and release of the scar, the size of soft tissue defect ranged from 5 cm×4 cm to 10 cm×8 cm. The size of TDAP flap ranged from 5.5 cm×5.0 cm to 10.5 cm×9.0 cm. Results All flaps survived completely with primary healing at both donor site and recipient site. The flaps of 3 patients were bulky and underwent second-stage skin flap thinning at 3 months after operation. All 7 patients were followed up 6-32 months, with an average of 15 months. The skin flaps were soft and elastic. According to the upper limb function evaluation system recommended by Chinese Society of Hand Surgery, sensory function was classified as S3+ in 2 cases, S3 in 1 case, S2 in 3 cases, and S1 in 1 case. The hand function was excellent in 2 cases, good in 4 cases, and fair in 1 case. There was no significant effect on shoulder movement.Conclusion The TDAP flap is an ideal method for serious scar contracture of opisthenar.
