内脏动脉动脉瘤的介入治疗

目的：介绍内脏动脉动脉瘤栓塞治疗新技术，材料与方法：１３例脾，肝等动脉动脉瘤，５例栓塞动脉瘤供血动脉，８例栓动脉瘤颈部或瘤腔，栓塞材料为弹簧圈，１１例采用了同轴微导管，各３例应用于“分阶段栓塞法”和双导管技术，结果：栓塞成功率９２．３％，９例有症状消失，１例栓塞过程中动脉瘤孔而手术，１例脾动脉瘤后部分脾梗塞，未予特殊治疗。栓后平均追踪时间３年３个月，均无再发出血或症状，先后１８人次ＣＴ，彩超和ＤＳ

Interventional Treatment of Visceral Arterial Aneurysm

Purpose:A new technique was discussed in embolotherapy of visceral arterial aneurysm.Materials and Methods:5 of 13 cases were embolized at the supply artery,other 8 cases at the lumen or cervix of the aneurysm.Coaxial microcatheter was used in 11 cases.Staging em bolization and double catheter were used in 3 cases seperately.Results:Success rate of em bolization was 92.3%.The symptoms in 8 cases disappeared.1 case underwent operation for perforation of aneurysm during the procedure.No special treatment was given to one patient with partial spleen infarct after embolization.Mean time of follow-up was 39 months,no re bleeding or symptoms appeared. Follow-up examination with CT,ultrasound or DSA of 18 cases all showed obliteration of aneurysms.Conclusion:Embolization sites should be decided according to the aneurysm wall,blood flow of supply artery and main trunk of organs.Staging embolizat ion could accelerate thromobogenesis of aneurysm and reduce the amount of spiral coil to avoid organ infarct.Double catheter could prevent regurgitation or dislocation of embol ic agents effectively.
