Endovascular recanalization and remodeling of abdominal aorta stent graft chronic total occlusion after failed extra-anatomic bypass surgery

Abstract

Objectives Chronic total occlusion (CTO) of the EVAR graft is a rare and serious complication. Traditionally, surgical intervention with prosthetic graft replacement or bypass graft implantation is performed. However, there are limited data in endovascular era. Methods We present a case of a 68-year-old male with a history of late EVAR graft occlusion treated with multiple surgical interventions (femorofemoral crossover, extra-anatomic bypass surgery, and thrombectomy) five years ago. Color Doppler ultrasound (CDUS) and computed tomography (CT) angiography revealed thrombosis of the entire bypass graft. Endovascular recanalization and remodeling of the abdominal stent graft CTO was performed with a combination of bare stents and stent grafts. Rupture of the stent graft occurred on the right limb. A second covered stent was placed. Results At 12-month follow-up, the patient was symptom free. Color Doppler ultrasound surveillance showed patent aortic stent graft and downstream arteries. Conclusions Endovascular recanalization of aortic stent graft CTO is a viable option in patients with failed bypass graft.
