Deciding on intervention for an iliac artery aneurysm depends primarily on its size and growth rate, alongside consideration of patient-specific factors. Generally, an aneurysm exceeding 3.0 cm in diameter is considered significant. While smaller aneurysms may be monitored with regular imaging, those reaching this threshold often warrant further evaluation for potential repair.
Addressing these aneurysms reduces the risk of rupture, a potentially life-threatening event. Intervention prevents thromboembolic complications, where blood clots can form within the aneurysm and travel to distal vessels, causing ischemia. Historically, open surgical repair was the standard treatment; however, endovascular aneurysm repair (EVAR) has emerged as a less invasive alternative, particularly for suitable anatomies and patient profiles.
