Objective:To analyze the interventional diagnosis and treatment of 13 children with hemoptysis and to improve the skills of pediatricians in the diagnosis and treatment of hemoptysis in children. Methods:The medical records including clinical manifestations,laboratory results,image data and treatments of 13 pediatric patients with hemoptysis given interventional treatment were retrospec-tively reviewed. Results:In 13 patients,including pneumonia(10 cases) and anaemia(9 cases),digital subtraction angiography(DSA) was performed for 21 times,and artery embolization therapy was performed for 14 times. Siderophages were identified in 7 patients. Four patients had massive hemoptysis,and 9 patients had non-massive hemoptysis. Five patients with collateral vessels were identified by ultrasonic cardiogram before interventional diagnosis,and 9 patients were identified by computed tomography angiography(CTA). Thirty-two abnormal pulmonary vessels were detected by DSA. Twenty-five(78.125%) of them were aberrant bronchial arteries,and seven of (21.875%) them arose from non-bronchial systemic arteries. Conventional treatments,including hemostatic agents,oxygen supplementation,ventilation support and hemoglobin maintaining,were administrated. Fourteen patients required bronchial artery em-bolization(BAE) treatment; the hemoptysis disappeared for all the patients three days after BAE; two of them were detected to have contract leaking to mediastinum,four of them had chest pain,one of them had complication of femoral arterial thrombosis. Conclusion:Echocardiography(UCG) combining CTA plays significant role in screening of pediatric hemoptysis suspecting to be aberrant vessels,and DSA is the golden standard for diagnosis. Occluder em-bolizing aberrant vessels has good effect of hemostasis. Aberrant vessel embolization by occluder has high quality in hemostasis,safety and stability,which is worth popularizing.
