DSA在腹主动脉瘤腔内隔绝术中的应用价值

目的：探讨数字减影血管造影（ＤＳＡ）在腔内隔绝术（ＥＶＧＥ）腹主动脉瘤（ＡＡＡ）中应用价值。方法：ＤＳＡ监控下将人造血管－支架复合体导入动脉瘤腔内，造影及透视下定位，使移植物固定于瘤体上下两端，将瘤腔与主动脉血流隔绝。结果：３８例中，即时操作成功率为９４．７４％，并发内漏４例，中转手术１例，移植物内血栓形成２例，死亡３例。结论：ＤＳＡ可实时、全程监控腔内隔绝术操作，在术中发挥测量、定位、即时评估、

DSA in endovascular graft exclusion for abdominal aortic aneurysms

Objective: To evaluate the role of DSA (digital subtraction angiography)in management of Endovascular Grafting Exclusion (EVGE) for abdominal aortic aneurysms. Methods: Monitored by DSA and fluorlscopy, stent graft complex was translated into the aneurysm sac via femoral arteries and were deployed at the proximal and distal necks to exclude the sac from circulation. Results: The success ratio of deployment was 94.74%. Endoleaks occured in 4 cases. One case was converted to open surgery because of sac rupture 4 days after deployment. Thromboses occurred in 2 cases. Three patients died. Conclusion: DSA can monitor EVGE on real time throughout the whole procedure. It can meet the needs of measurement, location, evaluation, detecting and correcting complications. Moreover, it provides large visual field and operating space, making it a very important monitoring method for EVGE.
