经桡动脉入路在神经介入的发展与应用

Development and application of transradial artery access in neurointervention

神经介入是在数字减影血管造影系统支持下,经皮穿刺相应血管,采用血管内导管操作技术,对累及神经系统的血管病变进行诊断和治疗的一种新兴微创技术。传统的手术入路是经股动脉入路,后随着经桡动脉入路(transradial access,TRA)在心血管领域的广泛使用以及带来的显著成效,神经介入医师开始思考TRA能否同样适用于神经介入领域。文章综合TRA的进展及其在神经介入领域安全性与可行性的研究与应用,进行一系列归纳总结,并对未来的研究进行展望。

Neurointervention is an emerging minimally invasive technique for the diagnosis and treatment of vascular lesions involving the nervous system by percutaneous puncture of the corresponding blood vessels and the use of intravascular catheterization techniques under the support of digital subtraction angiography(DSA)system.Traditionally,transfemoral access(TFA)has been used.With the widespread use of transradial access(TRA)in the cardiovascular field and the remarkable effect it has brought,neurointerventionists have begun to consider whether TRA can also be applied to the field of neurointervention.In this review,we summarize the literature about the application of TRA and researches assessing its feasibility and safety in the field of neurointervention.Then we propose future directions for this technique.
