Inferior vena cava thrombosis is a rare occurrence after an orthotopic liver transplant that is associated with a high rate of retransplant and mortality. There is no consensus regarding the optimal therapeutic strategy. Surgical management, including thrombectomy with revision of the cavocaval anastomosis, has been described. With the use of endovascular therapies, several minimally invasive approaches are available that are effective and avoid the high morbidity associated with reoperative surgery. We describe our successful experience using an approach after a liver transplant in which the inferior vena cava thrombosis in a patient presenting with acute renal failure, anorexia, weight loss, and fatigue using an ultrasound-accelerated, catheter-directed thrombolysis platform in conjunction with systemic anticoagulation.
