  • BASIC RESEARCH ON THE MECHANISM OF VENOUS REVERSE FLOW IN REVERSE-FLOW ISLAND FLAP

    Objective To investigate the basic mechanism of venous flow in reverseflow island flap. Methods Recent relevant literature on the mechanism of venous reverse flow in reverseflow 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.

  • 吻合血管逆行血供的游离穿支皮瓣修复四肢复杂创面

    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。
