In 2008 we witnessed a rapid advancement in stent technology, which is reflected in the high number of case reports, publications of case series, and randomized trials. Stents not only served for a combined intrasaccular and extrasaccular treatment of challenging aneurysms but also assisted the revascularization in acute and chronic ischemic conditions of the neurovascular system. Although a self-expanding nitinol semiopen cell stent is currently used for intracranial occlusive disease, a new retrievable closed-cell designed stent is widely used for aneurysms because of its easy delivery through a microcatheter in frequently tortuous head and neck as well as cerebrovascular circulation (Figure 1). However, despite numerous publications in the field, the widespread acceptance of the use of stents to routinely treat carotid stenosis awaits the results of the multicenter randomized clinical trials that should be available in 2009. The role of interventional neuroradiology in the treatment of acute ischemic stroke continues to expand and excite interest.
2008年，我们见证了支架技术的飞速发展，这体现在大量的病例报告、病例系列出版物以及随机试验中。支架不仅用于对具有挑战性的动脉瘤进行瘤内和瘤外联合治疗，还辅助神经血管系统急性和慢性缺血性疾病的血管重建。尽管目前一种自膨胀镍钛诺半开放式细胞支架用于颅内闭塞性疾病，但一种新型可回收封闭式细胞设计支架因其易于通过微导管在常呈迂曲状的头颈部以及脑血管循环中输送，而被广泛用于动脉瘤治疗（图1）。然而，尽管该领域有大量出版物，但支架常规治疗颈动脉狭窄的广泛应用仍有待2009年公布的多中心随机临床试验结果。介入神经放射学在急性缺血性卒中治疗中的作用持续扩大并激发人们的兴趣。
