The Endovascular Embolization of an Isolated Internal Iliac Artery Aneurysm: A Case Report.

While isolated internal iliac artery aneurysms (IIIAAs) are rare entities, they are associated with a high mortality rate if ruptured. IIAAs are usually asymptomatic and can be discovered accidentally during imaging for any other causes. The treatment options vary according to the signs, symptoms, size of the aneurysm, and the patient's general condition. While surgery used to be the first option of treatment earlier, with the advances in the field of endovascular intervention, endovascular repair of IIIAA has emerged as the first option of treatment if applicable.
