To pool the data of studies about thrombolysis in pulmonary thromboembolism (PTE) and evaluate the efficacy and safety of thrombolysis.
The randomized clinical trials (RCTs) that compared the efficacy or safety of thrombolysis and anticoagulation in massive or submassive PTE were chosen from MEDLINE disks from 1966 to May of 2003 and CBM disks from 1978 to May of 2003. A meta-analysis was employed to evaluate the results of the two therapies.
Twelve RCTs including 884 cases were analyzed. Compared with anticoagulation, the total OR of mortality and recurrence of patients with PTE treated with thrombolysis were 0.975 (95% CI 0.504 - 1.886) and 0.653 (95% CI 0.378 - 1.127) respectively, non-significant difference (P > 0.05). The total OR of bleeding in thrombolysis was 2.461 (95% CI 1.636 - 3.702, P < 0.01).
Compared with anticoagulation, thrombolysis cannot reduce the mortality or recurrence of PTE. Thrombolysis increases the risk of complication of bleeding.
