摘要
目的: 探讨将血管内支架置于动脉瘤附近载瘤动脉后发生的血流动力学改变,为动脉瘤的载瘤动脉内支架治疗提供实验依据。材料与方法: 向6 只犬7 个颈总动脉侧壁动脉瘤附近载瘤动脉内置入血管内支架,而后作血管造影,比较支架置入前后瘤腔闭塞及载瘤动脉通畅情况。结果: 7 个动脉瘤载瘤动脉内支架置入后3 天瘤腔均发生闭塞,载瘤动脉保持通畅;3 周后瘤腔仍见闭塞且载瘤动脉保持通畅。结论: 向动脉瘤附近载瘤动脉内置入血管内支架,可有效地闭塞动脉瘤。
Objective: To study the dynamic changes after intravascular stent placement in the parent artery near aneurysm and to obtain experimental data used for intravascular stent therapy of aneurysm.Materials and Methods:The stent was implanted in the parent artery near each aneurysm in 6 dogs. Follow up angiography was performed in order to compare the obliteration degree of aneurysm cavity and the patency of parent artery before and after the procedures.Results:Seven aneurysms were obliterated and parent arteries remained patency 3 days, even 3 weeks, after the procedure.Conclusion: Aneurysm can be effectively obliterated by the stent implanted in the parent artery near the aneurysm.
