Coil embolization of iliac artery aneurysms developing after abdominal aortic aneurysm repair with a conventional bifurcated graft

Endovascular Treatment of Isolated Bilateral Common Iliac Artery Aneurysms Using Iliac Branched Stent Graft

Endovascular treatment of isolated bilateral common iliac artery aneurysm (CIAA) requires salvage of at least one internal iliac artery to prevent complications such as ischemic buttock claudication. We treated a case of bilateral CIAAs using an internal iliac branched stent graft. We report a case of a 58-year-old man who presented with bilateral CIAAs. The left internal iliac artery was occluded with coil embolization. The right internal iliac artery was saved by using a branched stent graft. The aneurysms were excluded with conventional endovascular aneurysm repair. Completion angiography showed technical success. Follow up computed tomography angiogram at three months showed complete exclusion of bilateral CIAAs, no endoleaks, and patent right internal iliac artery. There was no pelvic ischemic complication. We treated successfully a case of isolated bilateral CIAAs using an iliac branched stent graft.

Endovascular treatment of bilateral common iliac artery aneurysms using bifurcated-unibody stent grafts

BACKGROUND

Endovascular treatment of bilateral common iliac artery aneurysms (CIAA) is a promising alternative to open surgical repair. However, endovascular treatment is challenging when the CIAAs have short proximal necks and internal iliac artery needs to be preserved.

METHODS/RESULTS

We report a case of a 62-year-old man who presented with bilateral CIAA with short proximal necks, with the right-side aneurysm extended into the internal iliac artery. The aneurysms were successfully excluded by using a bifurcated-unibody stent graft on the left with preservation of its internal iliac artery; a conventional tubular covered stent was used on the right with occlusion of its internal iliac artery. In addition, an aorta-bi-iliac artery stent was used to provide extended proximal landing zones for the iliac stents.

CONCLUSIONS

Endovascular repair using an iliac bifurcated-unibody stent graft can be a useful approach for the treatment of CIAAs. An aorta-bi-iliac endograft may also be needed to provide a reliable landing zone when the proximal neck of the iliac aneurysm is short.

Endovascular reconstruction of iliac artery bifurcation atherosclerotic disease with the kissing technique

A 71-year-old male patient with severe left buttock and lower-extremity claudication due to iliac artery bifurcation stenoses was referred to our institution for endovascular treatment. A 'kissing' technique was used in order to dilate the proximal parts of both internal and external iliac arteries and avoid compromization of the internal iliac artery during proximal external iliac artery stenting. A balloon expandable stent was inserted via a left ipsilateral retrograde access to the narrowed origin of the left external iliacartery and a balloon catheter via a right contralateral access inside the origin of the left internal iliac artery. Simultaneous balloons inflation restored full patency of both vessels. Twelve months later the patient is doing well, free of buttock or lower-extremity claudication symptoms. For iliac artery bifurcation atherosclerotic disease, endovascular repair with the 'kissing' technique can achieve a complete bifurcation reconstruction offering significant clinical benefit in selected patients.
