目的:探讨X线胸片正常咯血患者病因。方法:X线胸片正常咯血患者70例行血常规、高分辨CT、纤维支气管镜、心脏彩超、数字减影肺血管造影等检查。结果:确诊64例(91.40%),其中急慢性支气管炎13例(18.57%),支气管扩张11例(15.71%)、支气管肺癌11例(15.71%),支气管内膜结核8例(11.43%),动静脉畸形5例(7.14%),心脏病4例(5.71%),肺结核2例(2.86%),支气管腺瘤2例(2.86%),肺栓塞4例(5.71%),血液病2例(2.86%),肺小血管炎2例(2.86%),原因不明6例(8.57%)。结论:支气管炎症、支气管扩张、支气管肺癌、支气管内膜结核是X线胸片正常咯血患者主要病因,老年人肺癌多见。
Objective: To investigate the etiology of patients with normal hemoptysis on X-ray. Methods: Seventy patients with hemoptysis with X-ray chest radiography were examined with blood routine, high-resolution CT, bronchofibroscopy, echocardiography and digital subtraction pulmonary angiography. Results: 64 cases (91.40%) were diagnosed as acute and chronic bronchitis, including 13 cases (18.57%) of acute and chronic bronchitis, 11 cases of bronchiectasis (15.71%), 11 cases of bronchogenic carcinoma (15.71%) and 8 cases of bronchial tuberculosis , Arteriovenous malformation in 5 cases (7.14%), Heart disease in 4 cases (5.71%), Tuberculosis in 2 cases (2.86%), Bronchial adenoma in 2 cases (2.86%), Pulmonary embolism in 4 cases (5.71% Cases (2.86%), pulmonary vasculitis in 2 cases (2.86%), unexplained 6 cases (8.57%). Conclusion: Bronchitis, bronchiectasis, bronchial lung cancer and endobronchial tuberculosis are the main causes of hemoptysis in normal chest X-ray and lung cancer is common in the elderly.
