Abstract
Purpose: We aimed to investigate the long-term outcomes of patients undergoing hybrid catheter intervention for acute massive pulmonary thromboembolism.Material and Methods: Twenty-five patients with hemodynamic impairment were treated with mechanical thrombus fragmentation, an intrapulmonary injection of mt-PA, and manual clot aspiration between August 1999 and June 2002. All patients were discharged after the procedure. Patients’ statuses were checked by medical record examinations and telephone interviews. The median follow-up was 141 months (115-168 months).Results: Ten patients died during follow-up, five for malignancy, three for septic shock, one for cerebral infarction, and one for heart failure. One patient had recurrence of pulmonary thromboembolism because of drug withdrawal by self-judgment. No chronic pulmonary thromboembolism was observed. The 1-year, 5-year, and 10-year survival rates were 87.5 ±6.8%, 83.3±7.6%, and 74.5±9.0%, respectively.Conclusion: Patients who undergo hybrid catheter intervention for acute massive pulmonary thromboembolism show good long-term outcomes.
