ABSTRACT

Objective To analyze retrospectively the effect on patency of arterial bypasses combined with arteriovenous fistulae in patients with poor run-off. MethodsA retrospective analysis was made based on twenty-six patients with severe lower extremity arteries ischemia and poor run-off, undergoing arterial bypasses combined with arteriovenous fustulae. ResultsAmong the 28 diseased extremities in 26 patients,14 cases received bypass combined with deep arteriovenous fistulae(saphenous vein),and twelve underwent operations combined with superficial arteriovenous fistulae(popliteal vein,tibialis posterior vein).The short term patency rates in these two groups were both 78.6%.The two year′s patency of the bypasses combined with deep fistulae was 78.6%,that of combined with superficial fistula was 57.1%.ConclusionsArtery bypasses combined with arterovenous fistulae could improve the patency rates of the synthetic grafts in patients with severe lower extremity arteries ischemia and poor run-off.
