The clinical valve of microvascular anastomotic devices in the repair defects of lower extremity with free flap / 中华显微外科杂志

ABSTRACT

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 microvascular anastomotic devices was performed.Patient charts were reviewed for age,sex,etiology of defect,location of defect,flap type,anastomotic technique,complications and flap survival.Results No patients had an arterial or venous anastomosis revised.The vascular anastomosis patency 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 Microvascular anastomotic devices have effective vessel anastomoses in lower extremity microvascular reconstruction.Thus,it presents an ideal tool for lower extremity microsurgical reconstruction.
