Isolated aneurysms of the hypogastric artery are very rare and account for between 0.04% and 0.4% of all intra-abdominal aneurysms. In 85% of cases they are monolateral and are present in association with an aneurysm of the infrarenal abdominal aorta and of the common and external iliac arteries, they make up part of a poly-aneurysmal disease. Unless the patient is an extremely poor condition, surgical treatment is generally indicated for aneurysms greater than 3 cm; close monitoring of those with smaller aneurysms is recommended. Two patients presented with isolated aneurysm of an internal iliac artery which had developed several years after aortoiliac surgery. The one received surgical treatment; the other, who was in poor general conditions and at high risk for surgery, underwent endovascular embolization. Both procedures were successful, with a current follow-up between 15 and 18 months. Endovascular embolization, as performed in the 2nd patient, provided an alternative to the surgical procedure. After injection in the aneurysmal sac of the Gianturco spirals, a covered stent was placed in the iliac axis to exclude the inflow of the hypogastric artery. According to our experience of 2 patients, the one treated surgically and the other submitted to a less invasive endovascular procedure, we can state that both methods are practicable. The final choice lies with the vascular surgeon, after weighing the multiple factors that each case involves.
