Evidence summaries

Bifurcation Grafts for Aortoiliac Occlusive Disease

Five-year patency rates of bifurcation grafts appears to exceed 80%. Level of evidence: "B"

A systematic review 1 including 23 studies with a total of 6 149 subjects was abstracted in DARE. The pooled risk of operative mortality was 4.4%. Estimated 5-year limb-based patency rates for patients with intermittent claudication were 91% compared to 87.5% for patients with critical ischaemia. Patient-based patency rates were 85.8 and 80.4% respectively.

Comment: The quality of evidence is upgraded by good review methodology and consistency of results.
