There is a growing preference among neurointerventionalists for transradial access (TRA) over transfemoral access (TFA) due to improved patient satisfaction, recovery time and reduced access site complication, but using balloon guide catheters (BGCs) in the radial artery remains a challenge. We report our experience in successfully using the 0.087" inner diameter Walrus BGC without a sheath via the radial artery for non-emergent neurointerventions.
Describe the technique for safely accessing the radial artery using the sheathless Walrus balloon guide catheter.
A retrospective chart review of thirteen consecutive patients who underwent intervention with radial artery access with a sheathless Walrus BGC was performed.
All twelve procedures were performed successfully with no instances of conversion from TRA to TFA. There were no significant procedural or access site complications. The mean radial diameter was 2.51 mm.
The Walrus 0.087" ID BGC is an effective tool that can safely be used via the radial artery using a sheathless approach, which helps to maximize the size of the catheter that can be used. This is the first instance of our knowledge of this technique being utilized for neurointerventions and therefore could be used to expand the indications for TRA for a wider range of procedures.
由于患者满意度提高、恢复时间缩短以及穿刺部位并发症减少，神经介入医生越来越倾向于经桡动脉入路（TRA）而非经股动脉入路（TFA），但在桡动脉中使用球囊导引导管（BGC）仍然是一项挑战。我们报告了我们成功地通过桡动脉使用内径为0.087英寸的无鞘海象BGC进行非急诊神经介入的经验。
描述使用无鞘海象球囊导引导管安全进入桡动脉的技术。
对连续13例使用无鞘海象BGC经桡动脉入路进行介入治疗的患者进行回顾性病历审查。
所有12例手术均成功完成，无TRA转为TFA的情况。没有明显的手术或穿刺部位并发症。桡动脉平均直径为2.51毫米。
内径为0.087英寸的海象BGC是一种有效的工具，可以通过无鞘方法安全地经桡动脉使用，这有助于最大化可使用导管的尺寸。据我们所知，这是该技术首次用于神经介入，因此可用于扩大TRA在更广泛手术中的适应症。
