Abstract
Needle hole bleeding from polytetrafluoroethylene (PTFE) grafts causes blood loss and prolongs vascular procedures. Past studies have shown the cyanoacrylate glues to polymerize rapidly and cause minimal tissue toxicity. This study was undertaken to evaluate the efficacy of ethyl-2-cyanoacrylate glue (Krazy Glue, KG) in obtaining prompt hemostasis in vascular anastomoses in a heparinized canine model. KG effected complete hemostasis in a significantly shorter time than oxidized cellulose and digital pressure in 18-gauge needle holes in PTFE grafts, graft to graft end-to-end anastomoses, and end of graft to side of artery anastomoses. The only limitation of KG was the development of a glue-adventitia plaque on the arterial side of some of the PTFE-artery anastomoses, causing the need for regluing. KG is an ideal agent for sealing defects in PTFE grafts.
