目的：探讨数字减影血管造影（ＤＳＡ）在腔内隔绝术（ＥＶＧＥ）治疗腹主动脉瘤（ＡＡＡ）中的应用价值。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、发现并发症并监控纠正的作用。ＤＳＡ视野开阔，使用方便，是实施ＥＶＧＥ的重要监控手段。
Objective: To investigate the value of digital subtraction angiography (DSA) in the treatment of abdominal aortic aneurysm (AAA) with endovascular exclusion (EVGE). Methods: Under the supervision of DSA, the artificial blood vessel-scaffold complex was introduced into the lumen of the aneurysm, and it was positioned under contrast and fluoroscopy. The graft was fixed on the upper and lower ends of the tumor and the tumor lumen was isolated from the aortic blood flow. RESULTS: Of the 38 cases, the immediate success rate was 94.74%, with endoleak in 4 cases, transfer surgery in 1 case, graft thrombosis in 2 cases, and death in 3 cases. Conclusions: DSA can be used to monitor intraluminal exclusion procedures in real time and throughout the procedure. It can be used to perform measurements, localization, immediate assessment, detection of complications, and monitoring of corrective actions. DSA’s broad vision and ease of use are important monitoring tools for implementing EVGE.
