Objective To investigate the basic mechanism of venous flow in reverseflow island flap. Methods Recent relevant literature on the mechanism of venous reverse flow in reverseflow island flap wereextensively reviewed. Results The mechanism of venous reverse flow was a multifactorial phenomenon. “Communicating and collateral by pass route” and “incompetent valve route” were two theories. Conclusion The two routes of venous reverse flow in reverse-flow island flap coexistand complement each other.

目的 总结吻合血管逆行血供的游离穿支皮瓣修复四肢复杂创面的疗效。 方法 2019年11月—2020年12月,采用吻合血管逆行血供的游离穿支皮瓣修复16例四肢复杂创面。男12例,女4例;年龄17~75岁,中位年龄49岁。损伤部位:小腿、足踝14例,手臂2例。软组织缺损范围为7.0 cm×3.5 cm~27.5 cm×8.5 cm。临床诊断为开放性骨折伴不同程度骨、肌腱外露。受伤至手术时间10~35 d,平均17 d。采用股前外侧皮瓣7例,旋髂浅动脉浅支皮瓣9例;皮瓣切取范围为8 cm×4 cm~28 cm×9 cm。供区直接皮内缝合。 结果 15例皮瓣全部成活,未发生动静脉危象;1例旋髂浅动脉浅支皮瓣发生静脉危象,经探查处理后成活。术后所有患者均获随访,随访时间6~20个月,平均11.5个月。皮瓣颜色与周围皮肤接近,不臃肿,外形良好。末次随访时皮瓣两点辨别觉为8~10 mm,浅痛觉和触觉恢复良好。供区残留线性瘢痕,功能无影响。 结论 采用吻合血管逆行血供的游离穿支皮瓣修复四肢复杂创面安全可靠、创伤小,方便显微操作,可提高血管吻合质量。
