The purpose of this study was to evaluate the usefulness of a bifurcated stent-graft with a wide iliac limb end (WILE) in the treatment of abdominal aortic aneurysm (AAA) with a dilated common iliac artery (CIA) to avoid occlusion of the internal iliac artery (IIA). The WILE, covered with an expanded polytetrafluoroethylene graft which was constructed of large diameter stents according to the individual CIA diameter, was connected to a two-piece bifurcated stent-graft covering a polyester graft. The WILE was placed in eight dilated CIAs of six patients. All but one WILE fitted the dilated CIA well. One did not fit, and coil embolization of the leak was needed. All eight IIA derived from the dilated CIA avoided occlusion. Perigraft leak due to other causes was identified in another two patients. Limb kinking was observed in two patients. Our stent is useful in the treatment of AAA with dilated CIA to avoid occlusion of the IIA, and may extend the indication of endoluminal repair of AAA.

    • ...Ectatic CIAs may be a risk factor for development of an endoleak from the iliac attachment site of the stent-graft [2, 3]. To obtain a seal, the stent-graft can be extended into the external iliac artery (EIA) sacrificing the internal iliac artery (IIA); however, exclusion of the IIA may cause symptoms of buttock claudication, impotence, and bowel necrosis [4, 5] and should be avoided if possible [3]...
