The Use of Reverse Thermosensitive Polymer (LeGoo) for Temporary Vessel Occlusion in Clampless Peripheral Vascular Surgery

Abstract

Introduction: There is a need to develop methods of vascular hemostasis, which limit vessel trauma. LeGoo is a reverse thermosensitive polymer (poloxamer) which is a viscous liquid at room temperature, becoming a firm plug at body temperature. We aimed to describe early single center experience in clampless peripheral vascular surgery. Methods: Single surgeon experience using LeGoo during peripheral vascular surgery between February and October 2010 was analyzed. Results: LeGoo was used in 13 anastomoses in 11 patients. A satisfactory bloodless field without the use of conventional occlusion devices was achieved in 92% of anastomoses. At a median of 36 weeks follow-up, total conduit patency was 91%. Conclusions: In this small series, LeGoo was seen to be safe and effective in the provision of a clamp-free bloodless field in the context of peripheral vascular surgery. Prospective comparative study is necessary to determine performance against conventional vascular clamps.
