Abstract
Transradial access (TRA) has gained traction in neurointerventions as studies continue to demonstrate improved access site safety and equivalent end artery effectiveness when compared with traditional transfemoral techniques. Herein, we describe the technical nuances of obtaining TRA with a focus on distal TRA, left TRA, and sheathless TRA using larger bore catheters. We also discuss various strategies to avoid access site conversion if radial artery spasm or radial anomalies are encountered and offer some solutions for forming the Simmons catheter especially when it cannot be performed in the descending aorta. Lastly, we provide some insights regarding contraindications to TRA.
