Chronic Thrombosed Abdominal Aortic Aneurysm Treated by Endovascular Aneurysm Repair Using Bifurcated Endograft: A...

Thrombosed abdominal aortic aneurysms (AAAs) are rare. Owing to technical difficulties and concerns regarding inadequate device deployment, open surgical repair (OSR) has traditionally been performed rather than endovascular aneurysm repair (EVAR).

A 70-year-old male presented with bilateral intermittent claudication caused by a chronically thrombosed AAA, 53 mm in diameter. Although the occlusion extended from the AAA to the bilateral external iliac arteries, EVAR was planned based on the patient's clinical background. The occluded lesion was crossed using a bidirectional approach, and EVAR was successfully performed using a bifurcated stent graft.

This case report demonstrates that EVAR for a chronically thrombosed AAA can be performed by applying endovascular techniques commonly used to treat lower-extremity arterial disease.
