[The effectiveness of thrombolytic therapy in patients with massive and submassive pulmonary thromboembolism].
Thrombolytic therapy is the most effective therapy for massive pulmonary embolism (PTE). In this study we evaluated the symptoms, clinical and radiologic features and response to thrombolytic therapy in patients who had massive or submassive PTE. Thrombolytic therapy was administered for a mean period of 3 (1-5) hours to 19 patients with a mean age of 63.7 years who had the diagnosis of PTE based on symptoms which lasted for an average of 72 (2-240) hours and findings of echocardiography, spiral computed tomography (CT) angiography and perfusion scan. The patients to whom heparin infusion and oral anticoagulant treatment were given after thrombolytic therapy were evaluated. Bleeding as a complication was noted in six patients after thrombolytic therapy. Two patients died due to this complication. Control spiral CT angiography was performed to 12 of 15 (80%) patients who were initially diagnosed PTE by spiral CT angiography. While marked regression was noted in 5 (41.7%) patients in the early phase (second week), in 7 (58.3%) patients in the late phase (sixth month) PTE findings were completely disappeared. The median value of pulmonary artery pressure was 65 (45-70) mmHg before and 39.5 (30-45) mmHg after the treatment. Of the genetic factors studied before thrombolytic therapy, antithrombin III deficiency was found as the most common one. This study demonstrates that spiral thorax CT angiography is a very accurate diagnostic tool for the definitive diagnosis and transthoracic echocardiography is very useful for the rapid diagnosis and to decide for thrombolytic therapy, in especially patients who are not hypotensive and have submassive to massive PTE, and support the idea that thrombolytic therapy is life saving after reaching the certain diagnosis.
