Endovascular repair of iliac aneurysms is a minimally invasive procedure used to treat aneurysms in the iliac arteries, which supply blood to the lower limbs. The procedure involves inserting a catheter through the groin to place a stent graft in the iliac artery, sealing off the aneurysm and restoring normal blood flow.

This technique is preferred over traditional open surgery due to its lower risk, quicker recovery time, and better outcomes, especially for high-risk patients.
