We experienced 29 cases of patients with a chief complaint of hemoptysis who were performed pulmonary resection at the Department of Thoracic and Cardiovascular Surgery, Pusan Medical Center Hospital for 3 years from May 1990 to April 1993. The mean age of hemoptysis patients was 34.7 year old, and hemoptysis was most prevalent in third and fourth decades. The underlying lung diseases of hemoptysis patients were tuberculosis in 12[41.4% , bronchiectasis in 9[31.0% , lung cancer in 4[13.8% , aspergyllosis in 3[10.3% and pneumonia in 1[3.5% . Modes of hemoptysis were blood tinged in 7[24.1% , massive in 22[75.9% . Operation times were elective in 7[24.1% of all blood tinged hemoptysis, delayed in 20[69.0% , emergency in 2[6.9% out of massive hemoptysis. The cases of the definite bleeding focus found by bronchoscopy were 19 cases[65.5% . The operative procedures of hemoptysis were single lobectomy in 14[48.3% , pneumonectomy in 6[20.7% , lobectomy with segmentectomy in 5[17.2% , bilobectomy in 3[10.3% and segmentectomy in 1[3.5% . The postoperative results of hemoptysis were complete recovery in 27[93.0% , rehemoptysis in 1[3.5% which was treated by anti-Tbc medication completely, and hospital death in 1[3.5% which was brain metastasis of lung cancer. It was concluded that definitive diagnosis, preoperative control of hemoptysis and operation were important in the management of hemoptysis patients.
