In this study, muscle fascia removed from over the biceps femoris muscle was used as microvascular interpositional graft material in 67 rats. The faces of the cleaned fascia were rolled in order to form the luminal surface of the graft and were sutured in the from of a tube in different diameters and lengths. In group I, the grafts were 2.5mm in diameter and 2 to tmm in length in the common carotid artery. In group II, the abdominal aorta was preferred in order to apply longer grafts. These were prepared 4mm in diameter and 10-13mm in length.

The evaluations of the anastomoses were made 2 hours, 24 hours and 3 weeks after operation. Twenty anastomoses were examined by SEM for morphological inspection. At the end of 3rd week, patency rates demonstrated 22.2 and 23.1 percent in groups I and II respectively. Patent anastomoses revealed remarkable endothelialization on SEM by 3 weeks postoperatively. Technical difficulties have been also evaluated for this kind of anastomoses. Keywords : Graft patency. Microvascular anastomosis. Muscle fascia
