经导管动脉栓塞术治疗支气管动脉瘤

目的:探讨经导管动脉栓塞术(TAE)治疗支气管动脉瘤(BAA)的价值。方法:搜集经支气管动脉造影证实的BAA 2例,根据形态及部位不同,行不同方式TAE治疗,并临床随访。结果:囊状动脉瘤1例(微导管能顺利到达并通过),其远端实施球形PVA微颗粒栓塞止血,输出端及输入端分别用弹簧圈阻断血流,复查造影示支气管动脉远端血流阻断,BAA未见显示;梭形动脉瘤1例(距离支气管动脉起始部较远),其远端行球形PVA微颗粒栓塞,近端加注明胶海绵颗粒栓塞,复查造影BAA未见显示。结论:TAE是一种治疗BAA的微创、高效、可靠方法,不同形态及部位的BAA应选择不同方式的TAE。

Transcatheter arterial embolization therapy of bronchial artery aneurysm

Objective：To discuss the value of transcatheter arterial embolization（TAE） for treating bronchial artery aneurysm（BAA）.Methods：Two cases of BAA proved by bronchial artery angiography were treated by transcatheter arterial embolization in different ways according to their shapes and locations.Clinical follow-ups were done in one week,six months and one year.Results：In one case of saccular aneurysm,sphericl PVA micro-particles（500~700um） were injected in the distal part of vessel for stopping the bleeding;at the proximal and distal end of the aneurysm,metallic coils were introduced respectively for blocking of the blood flow.In another fusiform aneurysm（there is certain distance from the origin of bronchial artery）,PVA particles were injected in the distal end of aneurysm and for the proximal end gelatin sponge micro-particles were added for embolization.In the above two cases,the aneurysms were not found in the contrast examinations after the procedure.Conclusion：TAE is a minimally invasive,efficient and reliable method for the treatment of BAA.Different ways of TAE should be selected for different shapes and locations of BAA.
