[Percutaneous treatment of a common iliac aneurysm extending to the hypogastric artery with embolization and a covered endoprosthesis].
A case of iliac aneurysm treated percutaneously by endovascular stent graft (Wallgraft - Boston) and transcatheter embolization of internal iliac artery in order to prevent retrograde filling of the aneurysm from the patent hypogastric artery is presented. The initial radiographic evaluation included arteriography, and 2D and 3D spiral CT angiograms. This enabled analysis of the extent of mural thrombus, flow direction, as well as selection of stent graft and coil size. The procedure of embolization and implantation was technically uneventful. Post procedure 3D CT and arteriography demonstrated exclusion of the aneurysm, and return to a normal flow pattern. Follow-up at 6 and 12 months confirmed the stability of the results. Percutaneous treatment of common iliac artery aneurysms involving the hypogastric artery can be performed easily, especially in elderly patients. 3D CT is essential in assessing the endo and extra luminal characteristics of the aneurysm to insure optimal results and to detect complications.
