Endovascular aneurysm repair (EVAR) has become the preferred method, utilizing catheter-delivered stents to exclude the aneurysm from the circulation. However, once the aneurysm reaches a critical diameter or exhibits rapid expansion, intervention becomes necessary to prevent rupture.
Internal Iliac Artery Aneurysm as a Lower Abdominal Mass: Key Signs to Watch For
Definitive diagnosis relies heavily on advanced imaging. 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.
Anatomy and Pathophysiology The internal iliac artery bifurcates from the common iliac artery deep within the pelvis, branching into anterior and posterior divisions that supply the bladder, rectum, reproductive organs, and gluteal muscles. Clinical Presentation and Diagnosis The insidious nature of an internal iliac artery aneurysm means that it is frequently asymptomatic, discovered incidentally during imaging for unrelated conditions.

The long-term prognosis following successful treatment is generally favorable, with most patients returning to normal activity. For smaller, stable aneurysms that are asymptomatic, a strategy of vigilant surveillance through regular imaging may be appropriate.
