Dacron arterio-venous interposition graft: an access to circulation in patients on chronic hemodialysis. 
In a small percentage of cases, conventional a-v fistulae of the Brescia-Cimino type fail to provide long-term access facilities for chronic hemodialysis.  When homologous venous interposition grafts are not available, the surgeon is forced to seek foreign interposition material.  In three instances woven dacron arterio-venous interposition grafts were successfully constructed in the thigh, and uneventful hemodialysis was accomplished in all 3 patients.
