The primary objective of this study was to assess the incidence of new cerebral infarcts related to cardiac catheterization in patients explored through the right transradial approach.
This prospective study involved 41 consecutive patients with severe aortic valve stenosis. To assess the incidence of cerebral infarction, all patients underwent cerebral diffusion-weighted MRI before and after cardiac catheterization through the right transradial approach.
We detected only two patients (4.9%) with new, small, isolated acute cerebral diffusion abnormalities postcatheterization. All patients remained asymptomatic.
New cerebral lesions on diffusion-weighted MRI are infrequent in patients explored through the right transradial approach. Randomized studies are warranted to confirm for potential advantages of transradial approach versus the femoral approach in cardiac catheterization.
本研究的主要目的是评估经右桡动脉途径进行心脏导管插入术的患者中新发脑梗死的发生率。
这项前瞻性研究纳入了41例连续的重度主动脉瓣狭窄患者。为评估脑梗死的发生率，所有患者在经右桡动脉途径进行心脏导管插入术前后均接受了脑扩散加权磁共振成像检查。
我们仅检测到2例患者（4.9%）在导管插入术后出现新的、小的、孤立的急性脑扩散异常。所有患者均无症状。
经右桡动脉途径进行检查的患者中，扩散加权磁共振成像上新发脑病变并不常见。有必要进行随机研究以证实心脏导管插入术中桡动脉途径相对于股动脉途径的潜在优势。
