The authors attempted to insert a Gore-tex graft of 1 mm inner diameter to the rat aorta and renal artery with different techniques and different suture materials.

The telescoped technique was utilized for the anastomosis of the proximal part of the artery. They showed 80% patency of grafts up to 116 days with 10-0 ethilon and 83% patency up to 96 days with 7-0 silk in the rat aorta. In the rat renal artery, they showed 53.3% patency with 10-0 ethilon.

These results showed that Gore-tex grafts of a 1 mm inner diameter could be used for microvascular reconstructions but further laboratory experimentation is needed before clinical application.
