Embolization of hypogastric artery aneurysm: 17 cases

Surgical management of hypogastric artery aneurysm is associated with high morbidity due to hemorrhage and ischemia. Occlusion by embolization is an a ttractive alternative treatment. Between 1991 and 1995, we used Gianturco c oils to embolize 17 hypogastric aneurysms in 14 patients. All patients were men with a mean age of 77 years. Ten patients had previously undergone aor tic repair. Complete occlusion of the aneurysm was achieved in 16 cases but placement of an iliac stent was required in 1 case. Embolization failed in one case involving rupture of a large aneurysm. No complications were obse rved. Moderate buttock claudication was noted after bilateral embolization in three cases. Embolization of hypogastric artery aneurysm using coils res olves the long-term problems associated with surgical ligation. Extensive a neurysm of the origin to the bifurcation is the main indication for nonrese ctive treatment but embolization can also be a useful alternative to open s urgery for high-risk patients. Availability of stent grafts may extend the indication for endovascular treatment.
