Abstract

Thrombolysis was used in 13 procedures to treat eight patients with massive thrombosis of coronary aneurysms due to Kawasaki disease. The patients have now been followed for periods ranging from 2.5 years to 7.4 years subsequent to treatment. The procedures included intracoronary or intravenous infusion of urokinase and intravenous administration of tissue plasminogen activator. Thallium myocardial imaging, coronary arteriography and echocardiography were used for evaluation of the efficacy of the therapy and for follow-up studies. The latest time of treatment was 17 months after the onset of the disease. No new formation of massive thrombus was observed in any of the aneurysms. In five patients, eight of 13 procedures were judged to be successful. In the four patients with symptoms of myocardial ischemia, thrombolysis was undertaken immediately after the onset of symptoms. In the other patient, thrombolysis was attempted 36 days after the onset and produced remarkable improvement in the degree of ischemia. In the other four patients with no symptoms of ischemia, the therapy was undertaken when thrombus was detected in a coronary aneurysm. Aortocoronary bypass surgery was undertaken subsequent to the thrombolytic therapy in three patients, but proved satisfactory in only one patient. At follow-up, five patients have shown improvement in the degree of myocardial ischemia after treatment. Our results suggest that careful observation is needed to detect formations of thrombus in large coronary arteries for at least 1½ years after the onset of Kawasaki disease. Even if repeated thrombolytic therapy is required, it seems to be effective in checking the progression of ischemic heart disease.
