微血管吻合器在游离皮瓣修复下肢组织缺损中的应用

The clinical valve of microvascular anastomotic devices in the repair defects of lower extremity with free flap

目的探讨微血管吻合器在下肢组织缺损游离皮瓣修复中的应用价值。方法对于2013年5月至2013年11月，采用微血管吻合器治疗的42例下肢缺损游离皮瓣修复病例，分析患者年龄、性别、缺损原因、缺损部位、皮瓣类型、吻合应用细节、并发症和皮瓣成活情况。结果无患者发生动脉或静脉栓塞，血管通畅率为100％；皮瓣完全成活率为97．6％；术后并发症发生率为9．5％，包括1例部分坏死、1例植皮区部分坏死和2例血肿。无与微血管吻合器有关的术中和术后并发症。结论微血管吻合器在下肢游离皮瓣修复中有良好的血管吻合效果，是下肢组织缺损显微外科修复时的理想选择。

Objective To evaluate the clinical value of microvascular anastomotic devices in the reconstruction of lower extremity defects by free flap transfer. Methods A retrospective review of 42 consecutive patients who underwent lower extremity microvascular reconstruction performed from May 2013 to November 2013 by mierovaseular anastomotic devices was performed. Patient charts were reviewed for age, sex, etiology of defect, location of defect, flap type, anastomotie technique, complications and flap survival. Results No patients had an arterial or venous anastomosis revised. The vascular anastomosis pateney rates was 100% and the flap survival rate was 97. 6%. Total complication rate （9. 5% ） was due to 1 partial flap loss, 1 partial skin graft loss and 2 hematoma. There were no intraoperative or perioperative complications involving the use of a microvascular anastomotic device itself. Conclusion Microvaseular anastomotic devices have effective vessel anastomoses in lower extremity microvascular reconstruction. Thus, it presents an ideal tool for lower extremity microsurgical reconstruction.
