Clinical features and treatment of cryptogenic hemoptysis / 中国介入影像与治疗学

ABSTRACT

ObjectiveTo discuss the incidence,treatment and effect of cryptogenic hemoptysis (CH).MethodsPatients with CH were selected from 231 patients with hemoptysis according to clinical evaluation,chest radiography,fiberoptic bronchoscopy and CT scan,and the clinical data and treatment methods were retrospectively analyzed.ResultsFifty-three of 231 patients referred for CH,the incidence of CH was 22.94 ％ (53/231),of which 45 (45/53,84.91％ ) received internal conservative treatment and 8 (8/53,15.09％) received bronchial artery embolization (BAE).High resolution CT (HRCT) showed ground-glass opacities in 20 CH patients after hemoptysis.Bronchial arteriography showed abnormalities,including arterial enlargement and localized hypervascularity in 8 patients and systemic to pulmonary shunting in 3 patients.No recurrence of hemoptysis was observed during 1 to 8-year follow-up.ConclusionBleeding can be controlled in most of CH patients by internal conservative treatment,only a few patients with massive hemoptysis need BAE,and both treatments have good short and long term results.
