Submucosa of canine small intestine as an alternative medium-diameter autogenous arterial graft.

Background: Small intestinal canine submucosa has been used in previous studies as a large diameter arterial graft and has shown acceptable patency rates. The aim of our experimental study was to assess its effectiveness when it is used as an autogenous medium-sized diameter arterial graft (5-7 mm).

Methods: Fifteen mongrel dogs were included and underwent laparotomy under general anaesthesia.
