Endovascular management of aortic endograft occlusion

Abstract

Endovascular aortic repair is becoming the standard of care for abdominal aortic aneurysm. Despite aorta being a high flow system, there is still a definite risk of endograft occlusion. Management of occluded aortic endograft is highly controversial. Successful endovascular relining in aortic endograft occlusion is a technically demanding and forthcoming secondary intervention, not been studied extensively. We are reporting a case of aortic endograft thrombosis in a morbidly obese, 64-year-old gentleman with multiple comorbidities presenting with lifestyle-limiting claudication. The patient had a history of abdominal aortic aneurysm repair with aorto-uni-iliac device and femorofemoral bypass. The patient was managed by relining of aortic endograft with graft thrombectomy and snorkeling of the left renal artery. Postoperative course was uneventful. After 1 year of follow-up, the patient is free of symptoms with patent endograft. More empirical evidence is yet required to make the standard guidelines for the management of aortic endograft occlusion.
