Successful Thrombolysis of a Late Acute Thrombotic Occlusion of an Aortic Prosthesis after Endovascular Aneurysm Repair

A 79-year-old man with a previous endovascular aneurysm repair (EVAR) for a 5.4-cm abdominal aortic aneurysm presented 3 years after the procedure with sudden onset lower limb paralysis and pain. The diagnosis of acute aortic thrombosis within the aortic prosthesis graft was made and confirmed on computed tomography. Thrombolysis delivered into the graft via a radiologically placed catheter successfully dissolved the thrombus and resulted in improvement of the patient's symptoms. We discuss the presentation of, and role in management of thrombolysis in, this rare complication of aneurysm repair.
