HUANG Jing,ZHENG Yunyun,LI Ping, et al. Prophylactic embolization in the treatment of congenital bronchial artery-pulmonary circulation fistulas[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2018, 48(12): 921-924,928.
Abstract： Objective: To evaluate the curative effect of the prophylactic embolization in the treatment of congenital bronchial artery-pulmonary circulation fistulas (CBPF). Methods: A total of 11 children (6 males and 5 females), who had CBPF from the Second Affiliated Hospital of Wenzhou Medical University from Jan. 2016 to Dec. 2017, were diagnosed with selective bronchial artery angiography in the procedure of interventional occlusion of patent ductus arteriosus (PDA). The age of all patients ranged from 11 months to 12 years old. In 10 cases, whose fistulas were larger in diameter than adjacent bronchial artery, interventional occlusion was performed by either interlock fibered coils or pfm coils. Regular follow-up was done in 1, 3, 6 and 12 months after operation and once a year thereafter. Results: All patients’ PDA were successfully occluded. After PDA occlusion, the descending aortic angiography was applied, which showed that all 10 patients’ PDA were completely closed immediately, but 1 patient was left untreated due to the tortuosity of bronchial artery. During the follow-up, no patient had hemoptysis or other complications. Conclusion: Prophylactic therapeutic embolization is an effective way to protect patients who have CBPF. However whether it can protect against major hemoptysis remains unknown and requires long-term follow-up.
