Endovascular treatment of internal iliac artery aneurysms

Purpose: To describe a technique for percutaneous endovascular repair of in ternal iliac artery aneurysms. Technique: In a patient with an isolated internal iliac artery aneurysm and combined tight stenoses at the origins of the external and internal iliac arteries, interventional treatment consisted of coil embolization of the in ternal iliac artery and branches using the contralateral femoral approach. Balloon dilation of the external iliac stenosis occluded the internal iliac artery, and Palmaz stents were placed in the external iliac stenosis to ov ercome residual luminal narrowing. Conclusions: This one-step percutaneous technique allows total exclusion of the internal iliac artery aneurysm using coil embolization. This treatment may be an alternative to surgery in isolated internal iliac artery aneurys ms with Small orifices.
