Replacement of superior vena cava with EPTFE graft (30-50mm length) associated with creation of temporary bridge type distal arterio-venous shunt was investgated in dogs. Shunt ratio was 13-48%.
Eight of nine (88.9%) showed good graft patency in the dogs with A-V shunt examined by venography performed six months after the operation. On the other hand only tow of seven (28.6%) was patented in the dogs without distal A-V shunt.
Temporary bridge type distal A-V shunt was effective in the patency of the replaced EPTFE Graft.
Arterio-venous shunt with shunt ratio less than 48% made no cardiac failure in dogs.
Proper time to close temporary A=V shunt is more than six months after the operation.
