Internal iliac artery aneurysms are rare. In most instances, they do not cause symptoms unless they rupture. Mortality after rupture is about 50%. Aneurysm under 25-30mm in size can be watched with serial imaging - typically CT. Aneurysms > 25-30mm should be treated to avoid rupture. Endovascular repair is preferred to open surgery as it is safer, faster and effective.
