Randomized Controlled Trial Multicenter Study Comparative Study
Long-term results of a multicenter randomized study on direct versus crossover bypass for unilateral iliac artery occlusive disease.
To compare late patency after direct and crossover bypass in good-risk patients with unilateral iliac occlusive disease not amenable to angioplasty. ⋯ This study showed that late patency was higher after direct bypass than crossover bypass in good-risk patients with unilateral iliac occlusive disease not amenable to angioplasty. Crossover bypass should be reserved for high-risk patients with unilateral iliac occlusion not amenable to percutaneous recanalization.
