AFONSO, Cristina Toledo et al. Ruptured internal iliac artery aneurysm: case report. J. vasc. bras. [online]. 2009, vol.8, n.1, pp.92-96.  Epub 20-Mar-2009. ISSN 1677-5449.

Isolated internal iliac artery aneurysms are rare. They affect 0.1% of the population, and account for 1% of aortoiliac aneurysms. Patients are mostly asymptomatic, yet they can have abdominal pain, pulsatile mass in the hypogastrium or iliac fossa, or urinary, gastrointestinal or neurological compressive symptoms. Such aneurysms are likely to course with an acute abdomen, especially when ruptured. Early diagnosis of isolated internal iliac artery aneurysms is difficult, as they are more easily detected when larger or ruptured, which significantly raises their morbidity and mortality rate and determines a poor prognosis. Therefore, they are a therapeutic challenge. Surgical ligation has been the most common treatment; however, the endovascular approach has presented good outcomes, even in the event of ruptured aneurysms. A case of ruptured isolated iliac artery aneurysm diagnosed during a laparotomy (acute abdomen approach) is reported.
