THERE general agreement that if a defect exists in an essential blood vessel, it is best repaired with a piece of vessel from the same individual (autograft) or from an individual of the same species (homograft). The usefulness of homografts in vascular surgery has been amply demonstrated,1 but there are problems of procurement, preparation, sterilization, and preservation. It would be advantageous if it could be shown that a tissue other than vascular tissue could substitute for vessel wall. It occurred to us that a tough structure like the posterior rectus sheath with its peritoneal lining might have some possibilities. A review of the literature turned up the fact that Alexis Carrel2 once used a flap of peritoneum to repair a defect in the aorta of a cat, and three months later the vessel appeared to be patent. Recently, Sako and co-workers3 carried out some experiments with tubes
