PURPOSE: To clarify the short-term effect and long-term results of bronchial arterial embolization forhemoptysis in three groups with tuberculosis, idiopathic bronchiectasis and lung cancer. MATERIALS AND METHODS:This study invo l ved 54 patients who underwent arterial embolization for the control of hemoptysis. Among 54, thecauses of hemorrhage were; pulmonary tuberculosis(n=32), idiopathic bronchiectasis (n=15), and lung cancer(n=7).In all patients, em-bolization was performed using Gelfoam particles and three underwent additional coilemboliza-tion. After the procedure, patients were followed up for between 1 and 95 (mean, 36.7) months. Short-termresults were assessed on the basis of careful observation of patients for 1 month after ar-terial embolization andwere classified as either; successful, indicating complete cessation of he-moptysis for 1 month, or failed,indicating continuing hemoptysis or recurrence within 1 month. Long-term results were evaluated in patients inwhom the procedure was successful in the short term and who could be followed up for at least 6 months. Patientsshowed either complete remis-sion(CR), indicating complete cessation of bleeding during the observation period;partial remis-sion(PR), indicating complete cessation of hemoptysis with recurrent bloody sputum during theobservation period; or recurrence, indicating recurrent hemoptysis, and were grouped accordingly. RESULTS: Noserious procedure related complications occurred except for mild chest pain or fever, of which showed spontaneousrelief within a few day s. The overall short-term success rate was 7 9 .6 %(43/54); individual rates were 84.4%for pulmonary tuberculosis (27/32), 80% for idiopathic bronchiectasis (10/15), and 57.1 % for lung cancer (4/7).Long-term follow-up showed that complete remission was achieved in 24 of 43 cases (55.8 %).The respectivelong-term remission and recur-rence rates were 75 % and 25 % for bronchiectasis, 70.4 % and 29.6 % for pulmonarytuberculosis. While four lung cancer patients whose initial outcome was successful showed no recurrence ofhe-moptysis, three died within 3 months of embolization. CONCLUSION: Embolization of bronchial arteries using aGelfoam sponge is effective as initial treat-ment for moderate or severe hemoptysis caused by benign disease.During long-term follow up, high remission rates were achieved in pulmonary tuberculosis and idiopathicbronchiectasis pa-tients, while the shortest bleeding control was in cases involving lung malignancy.
