Endovascular Treatment of Extensive Acute Thrombosis Involving the Iliocaval and Renal Veins Associated with Chronic Caval Occlusion: A Case Report

Deep venous thrombosis (DVT) may present with a wide spectrum of clinical manifestations, ranging from asymptomatic cases to signs and symptoms associated with pulmonary embolism, depending on the location and extent of the thrombus. Extensive acute DVT accompanied by chronic caval occlusion may not be adequately treated with anticoagulation or catheter-directed thrombolysis alone. We present a case of extensive acute iliocaval and renal vein thrombosis associated with chronic inferior vena cava occlusion that was successfully treated using endovascular techniques, including rheolytic thrombectomy and stent insertion.
