Abstract
The use of 1-mm ID by 1-cm-long expanded polytetrafluoroethylene microvascular grafts in various positions in two experimental animals did not compare favorably with the use of autogenous vein interposition grafts in controls. Light microscopy and scanning electron microscopy showed that early fibrin deposition at the anastomosis lines is followed by fully activated coagulation of the grafts. Use of antiplatelet and anticoagulant drugs, changes in techniques, and alterations in the graft material are possible future directions for improved patency with expanded polytetrafluoroethylene microvascular grafts.Keywords
