Resumen

Aim: The aim of the present paper is to show the experience of the Plastic Surgery Division at the Universityof Chile Clinical Hospital, with the Coupler® anastomotic device Synovis Corp, Birmingham, AL for venous microanastomoses in patients undergoing reconstructive microsurgery. Material and Methods: A retrospective review of 48 consecutive patients with free flaps between March 2009 and in February 2013. All microsurgical venous anastomoses were performed with the Coupler® device and the arterial anastomoseswith interrupted or continuous 9-0 or 10-0 nylon sutures. The collected data were: personal and medical patient information, location of the defect, flap used, vessels diameter, arterial anastomoses, Coupler® used, time of anastomosis, postoperative complications, arterial and venous thrombosis. Results: A total of 48 free flaps were performed for reconstruction of lower extremity n = 25, 52.1%; head-neck n = 15, 31%; breast n = 5, 10.4% and upper extremity n = 3, 6.3%. The flaps used were: Anterolateral thigh or ALT n = 25, 52.1%, Radial n = 10, 20.8%, Deep Inferior Epigastric Artery Perforator or DIEP n = 5, 10.4%, Latisimus Dorsi n = 2, 4.2%, Rectus Abdominus n = 2, 4.2%, Fibula n = 2, 4.2%, Scapula n = 1, 2.1%, and Gracilis n = 1, 2.1%. The Coupler device average diameter used was 2.51 ± 0.46 mm. The average time for the venous anastomosis was 13.5 ± 7.3 minutes. A total of 4 flaps were lost 8.3%, none due to venous thrombosis. Conclusions: The Coupler® System for venous anastomoses is a safe, effective and quick methodfor microsurgical anastomoses, it is easy to learn and its implementation should be considered in every microvascular surgery center.Nota general
