Long-term results of aortoiliac angioplasty.

Results of percutaneous transluminal angioplasty of 141 iliac arteries in 112 patients are reported, with a follow-up period extending to 36 months. Initial technical success was achieved in 95.7%, 1-year patency in 91.3%, and accumulated 2- and 3-year patency in 89%. The role of outflow disease and ankle:arm index measurement and the importance of eliminating or significantly reducing the intra-arterial pressure gradients are discussed.
