[Experimental arterial microanastomoses].

The morphological changes in the walls of 40 arterial microanastomoses were studied in experiments. The initial signs of endothelization appear in 3 days and the process ends by the 9th-12th day. The tissue reaction to the different suture material is of the same type and its degree is not linked with the type of synthetic thread used. Minimum injury inflicted to the intima and the other coats of the vascular wall and pre- and postoperative use of acetylsalicylic acid are measures preventing occlusion and stenosis of the anastomosis.
