[Endovascular stent-grafts for the treatment of isolated iliac artery aneurysms: a report of 14 cases].
OBJECTIVE
To evaluate the efficacy of endovascular repair (EVR) for isolated iliac artery aneurysms (II AA).


METHODS
Fourteen patients were treated with transluminally placed endovascular stent-grafts from October 2004 to May 2006. In eight patients, the aneurysms involved the right common iliac arteries. In five cases, left common iliac arteries were involved. The aneurysm involved the left internal iliac artery and ruptured in the other case. Criteria for repair were a diameter over 3.0 cm for true aneurysms.


RESULTS
Technical success was achieved in all cases. Eight cases with right common iliac artery aneurysms were treated with bifurcated aorto-iliac stent-grafts after ipsilateral internal iliac artery embolization with coils. One case with right common iliac artery aneurysm involved the bottom of abdominal aorta was treated with AUI stent-graft and femorofemoral bypass. Five cases involved left common iliac arteries were treated with tubular stent-grafts after ipsilateral internal iliac artery embolization with coils. One case with ruptured left internal iliac artery aneurysm was treated emergent with tubular stent-graft after ipsilateral internal iliac artery embolization with coils. Aortography carried out immediately after the procedure showed the II AA were completely excluded by stent-grafts and no serious endoleaks both on the proximal or distal connections. One case with acute left ventricular dysfunction and alveolar edema postoperatively recovered after emergent treatment No complications in thirteen cases. All patients were followed up for a mean of 10.2 months (3 to 19 months) by CTA, no aneurysms enlargement, no stent-grafts migration, no endoleak, femorofemoral bypass was patent.


CONCLUSIONS
Endovascular repair of isolated iliac artery aneurysms is a minimally invasive,safe and feasible technique and provides good short-term patency. Long-term patency is followed.
