title: Comparison of fibrinolytic treatment with interruption of the inferior caval vein in the prevention of pulmonary embolism.
abstract: The procedure of interruption of the inferior caval vein is designed to prevent pulmonary embolism, but its effectiveness has yet to be compared with thrombolytic therapy. Sixty patients hospitalized for pulmonary embolism and proximal deep vein thrombosis were divided into two groups of 31 and 29 patients, respectively. The patients were selected because of persistent venous thrombosis in the inferior caval, iliac or femoral veins. The patients in the first group (mean age 53.2 years) were treated by interruption of the inferior caval vein. The second group of patients (mean age 57) received only fibrinolytic treatment. From those patients having caval venous interruption due to peri-operative myocardial infarction 1 died and 3 others presented pulmonary embolism (massive in two cases). No patients treated by fibrinolysis suffered from pulmonary embolism. Five patients died of cancer, 2 having had caval interruption, as opposed to only 2 having fibrinolysis. Eight patients undergoing surgery had a severe functional handicap. This study demonstrated a high recurrence of pulmonary embolism in patients with persistent venous thrombosis who were treated by interruption of the inferior caval vein. These patients also had a high morbidity. Fibrinolytic treatment (even in the presence of persistent venous thrombosis) appeared to be more effective in avoiding recurrence of pulmonary embolism.
