EndoFit stent-graft repair of isolated common iliac artery aneurysms with short necks.

Full Abstract

PURPOSE: To evaluate the feasibility and efficacy of repairing isolated iliac artery aneurysms with short proximal necks (<10 mm) by implanting the EndoFit stent-graft. METHODS: Seven patients (6 men; median age 73 years, range 70-78) were diagnosed with an isolated common iliac artery (CIA) aneurysm that featured a short proximal landing zone, complicating endovascular treatment. The median aneurysm diameter was 4.4 cm (range 3.5-7.0), and the median proximal neck length was 7 mm (range 5-9).The aneurysms were treated using the EndoFit stent-graft, which can be deployed in a short proximal landing zone. The modified technique involves the deployment of the graft directly above the aneurysm sac without obstructing the contralateral iliac axis, thus affixing the bare proximal stent in the terminal aorta. Follow-up was performed by clinical evaluation and computed tomography at 1, 6, and 12 months postoperatively. RESULTS: The EndoFit stent-graft was successfully deployed in all cases, with complete aneurysm exclusion. In 1 case, the deployment of a second cuff was necessary to secure complete aneurysm exclusion. The median follow-up was 18 months, during which no deaths occurred, and no endoleak or stent-graft migration was observed. Endograft thrombosis occurred in 1 case due to graft angulation caused by external iliac artery stenosis and kinking. None of the aneurysms has ruptured, and there have been no serious complications. CONCLUSION: Direct endoluminal repair of isolated CIA aneurysms with short proximal necks is feasible using this technique. Efficacy and long-term results are to be confirmed by larger scale series over a long time period.
