Common iliac aneurysm involving the hypogastric artery: treatment with embolization and covered stent graft placement

A case of iliac aneurysm treated percutaneously by endovascular stent graft (Wallgraft - Boston) and transcatheter embolization of internal iliac arte ry in order to prevent retrograde fitting of the aneurysm from the patent h ypogastric artery is presented. The initial radiographic evaluation include d arteriography, and 2D and 3D spiral CT angiograms. This enabled analysis of the extent of mural thrombus, flow direction, as well as selection of st ent graft and coil size. The procedure of embolization and implantation was technically uneventful. Post procedure 3D CT and arteriography demonstrate d exclusion of the aneurysm, and return to a normal flow patern. Follow-up at 6 and 12 months confirmed the stability of the results. Percutaneous tre atment of common iliac artery aneurysms involving the hypogastric artery ca n be performed easily, especially in elderly patients. 3D CT is essential i n assessing the endo and extra luminal characteristics of the aneurysm to i nsure optimal results and to detect complications.
