作者介绍了2例椎动脉远端小的、急性破裂的宽颈动脉瘤患者，这些动脉瘤不适合常规弹簧圈栓塞，而是通过双支架方法进行治疗，其中一个支架放置在另一个支架内。术后立即进行的血管造影显示动脉瘤充盈显著减少; 7天后观察到病变完全闭塞，6个月后在两个动脉瘤中得到证实。通过将一个支架放置在另一个支架内，可以降低支架渗透性，这可能导致显著的血流动力学变化，加速动脉瘤血栓形成。这种双支架方法可能代表一种治疗替代方案，特别是在传统血管内技术或支架支持弹簧圈栓塞不可行或被认为过于危险且禁忌手术治疗的小型宽颈动脉瘤病例中。
The authors present two cases of patients with small, acutely ruptured, wide-necked aneurysms of the distal vertebral artery that were not amenable to conventional coil embolization and were instead treated by means of a double-stent method in which one stent was placed inside another. Angiography performed immediately after the procedure revealed a significant reduction in aneurysm filling; total occlusion of the lesion was observed after 7 days and confirmed 6 months later in both aneurysms. By placing one stent inside the other, stent permeability can be reduced, which may result in significant hemodynamic changes with accelerated aneurysm thrombosis. This double-stent method may represent a therapeutic alternative, especially in cases of small, wide-necked aneurysms in which conventional endovascular techniques or stent-supported coil embolization is not considered feasible or is believed to be too dangerous, and surgical treatment is contraindicated.
