混合栓塞治疗合并支气管动脉-肺循环瘘肺咯血中的效果分析

Treatment of Bronchial Artery-Pulmonary Circulation Fistula Complicated with Pulmonary Hemoptysis by Mixed Embolization

目的:探讨混合栓塞对合并支气管动脉-肺循环瘘(B-P分流)的肺咯血的治疗效果。方法:对19例造影证实存在B-P分流的肺咯血患者的支气管动脉进行混合栓塞治疗。结果:治疗后3天内19例全部止血,术后半年随访无复发。结论:B-P分流发生于病变区域的血管网络,支气管动脉远端用明胶海绵碎块、PVA颗粒栓塞,明胶海绵长条栓塞相对细小主干,近端用羊毛钢圈栓塞,这样永久、完全栓塞病变区域血管网,能彻底防止咯血复发。

Objective： To investigate the therapeutic effect of the intervention treatment by means of mixed embolization to treat the bronchial artery- pulmonary circulation fistula complicated with pulmonary hemoptysis.Methods： 19 patients with bronchial artery- pulmonary circulation fistula complicated with pulmonary hemoptysis diagnosed by angiography of bronchial artery and then received embolotherapy. Results： All of 19 patients who received embolotherapy stopped bleeding within 3 days,and no one showed recurrence during six months follow- up.Conclusions： B- P shunt occurs in blood vessels network of lesion area. Fragments of the distal bronchial artery are embolized with gelatin sponge,PVA particles,and gelatin sponge strips can embolize the relative small trunk.While the proximal can be embolized by wool rims to block the vascular network permanently. Thus,it can completely embolize the vascular network at the lesion area and prevent recurrent hemoptysis thoroughly.
