Risk Factors and Associated Conditions Several factors contribute to the development of an internal iliac artery aneurysm , aligning closely with generalized vascular disease risks. Complications and Long-Term Outlook Untreated, an internal iliac artery aneurysm poses a severe risk of rupture, which carries a high mortality rate due to the difficulty of achieving rapid control of hemorrhage in the pelvis.

Definitive diagnosis relies heavily on advanced imaging. In complex cases where anatomy is unfavorable for endovascular techniques, open surgical repair remains a highly effective, albeit more invasive, alternative.
An internal iliac artery aneurysm represents a focal dilation of the internal iliac artery, the primary vessel supplying the pelvis and its numerous vital structures. The weakening of the arterial wall, often due to atherosclerosis, inflammation, or infection, creates a persistent pressure that causes the vessel to expand.

An aneurysm in this location is defined as a localized dilation exceeding 50% of the normal arterial diameter. Even without rupture, complications can arise from the mass effect of the aneurysm, including nerve compression leading to motor deficits or venous obstruction causing significant leg edema.
