A successful thrombolysis with tissue-type plasminogen activator in a case of pulmonary embolism after failed streptokinase therapy

A 76-year-old male patient diagnosed with acute, massive pulmonary embolism due to deep vein thrombosis of a lower extremity developed significant cardiovascular and respiratory instability. Subsequently, streptokinase infusion was administered over two hours. Spiral computed tomography was performed due to the persistent hemodynamic instability following the thrombolytic therapy. Computed tomography showed persistent massive pulmonary embolism. In the light of literature data, the patient was recommended for surgical pulmonary embolectomy, however he refused surgery. Therefore, he was administered intravenous recombinant tissue type plasminogen activator over two hours. Clinic status of the patient and radiological findings were significantly improved following therapy. The patient was discharged with effective anticoagulant therapy.
