In vivo and mechanical properties of peritoneum/fascia as a novel arterial substitute.

Objective: This study evaluates the efficacy of bovine peritoneum/fascia as an arterial substitute.

Methods And Outcome Measures: Twelve dogs underwent bilateral femoral artery patch angioplasty with a glutaraldehyde-fixed bovine peritoneal/fascial patch (PFA patch) on one side and polyester patch on the contralateral side. Arteriograms were performed just before vessel harvest at 1 and 6 months, and vessels were evaluated for aneurysms and inflammation.
