The clinical study on etiology and diagnostic procedures of hemoptysis in children / 中国小儿急救医学

ABSTRACT

Objective The purpose of the study was to investigate the causes of hemoptysis and ex-plore the diagnostic procedures for hemoptysis in children. Methods The medical records of 42 children with hemoptysis admitted to the Respiratory Department of Hunan Children′s Hospital from June 2012 to June 2015 were collected by a retrospective study. The causes of hemoptysis were classified by pathogenesis,and the diagnosis of hemoptysis was evaluated in this study. The final diagnosis was divided into clear diagnosis and the cause was unknown. Results A total of 41(97. 6%) cases were diagnosed,1(2. 4%) case was not diagnosed. In 42 cases of hemoptysis,infection was the main cause of the disease,including 8(19. 0%) cases of pneumonia and 5(11. 9%) cases of bronchitis,and the following causes were bronchial artery fistula(10/42,23. 8%),idiopathic pulmonary hemosiderosis(8/42,19. 0%),bronchiectasis(5/42,11. 9%),pulmonary vascular malformation with pulmonary hypertension(3/42,7. 2%),pulmonary tuberculosis(2. 4%),bronchi-al foreign body(1/42,2. 4%) respectively. Thirteen cases of respiratory tract infection,and 5 cases of bron-chiectasis were diagnosed by chest CT,10 cases with pulmonary artery fistula were diagnosed by digital sub-traction angiography,8 cases of pulmonary hemosiderosis,1 case of pulmonary tuberculosis,and 1 case with bronchial foreign body were diagnosed by fiberoptic bronchoscopy. Three cases of pulmonary vascular malfor-mation and pulmonary hypertension were diagnosed by row helical CT angiography and cardiac color ultra-sound. Conclusion Hemoptysis in children is a heterogeneous group of respiratory disorders. Most causes could be identified by using the diagnostic procedures. Other factors, including medical history, CT, fiber bronchoscopy,multidetector CT angiography, cardiac color ultrasound and digital subtraction angiography, play important roles in the diagnosis of hemoptysis in children.
