Kissing stents are commonly placed for aortic bifurcation lesions with disappointing mid and long term patency compared to common iliac stents. Covered stents may provide better patency. We reviewed outcomes of percutaneous placement of kissing covered iliac stents for aortic bifurcation atherosclerotic lesions compared to non-covered stents.

A retrospective review of patients with aortic bifurcation disease treated with bilateral common iliac kissing balloon expandable stents was performed for cases between 1/1/2002 and 4/1/2007. Fifty six consecutive patients were identified and divided into two groups: non-covered stents (NCS) and covered stents (CS). Thirty one patients (13 males, median age 62 years, range 38-82) received NCS and 25 patients (18 males, median age 60 years, range 39-77) received CS. Indications for stent placement included claudication in 44 patients (24 NCS and 20 CS) and limb-threatening ischemia in 12 (7 NCS and 5 CS). Kaplan-Meier survival analysis was performed.

Technical success was achieved in 100% of patients in both groups. Immediate improvement in ankle-brachial indexes was seen in 29/31 (93%) in the NCS group and 25/25 (100%) in the CS group with average increase from 0.64 to 0.86 for NCS and 0.64 to 0.92 for CS with no significant difference between the groups. Major complications occurred in 3/31 (9%) patients in the NCS group and 2/25 (8%) patients in the CS group. Median follow up was 21 months (25 months for NCS vs 20 months for CS; range 1-56). Primary patency rates at 1 and 2 years were 84% and 76 % for NCS and 96% and 96% for CS (p=0.041)

Covered kissing stents for aortic bifurcation disease provide better patency than non-covered stents at 2 years.

Kissing common iliac stents are prone to stenosis and thrombosis, and covered stents may improve the outcome in this sub-group of patients.
