Summary
The Rist catheter enables successful transradial access (TRA) for complex neurointerventions, demonstrating lower conversion rates compared to traditional methods. This technique offers a safe and effective alternative for vascular procedures.
Area of Science:
- Interventional Neurology
- Vascular Access Techniques
- Neuroendovascular Surgery
Background:
- Transradial access (TRA) is gaining traction for neurointervention.
- Existing methods have conversion rates of 8.6-10.3% due to tracking issues, inadequate support, or radial artery spasm.
Purpose of the Study:
- To evaluate the safety and efficacy of the Rist Radial Access System for neurointerventions.
- To present an institutional protocol for utilizing the Rist system.
Main Methods:
- Multicenter, retrospective case series.
- Inclusion of 152 patients undergoing neurointerventions with the Rist Radial Access System.
- Documentation of procedural details, including radial artery diameter and use of intermediate catheters.
Main Results:
- Successful completion in 96.1% of cases.
- Low conversion rates: 1.3% to femoral access and 1.9% to alternative radial catheters.
- Minimal complications: 0.7% minor access site and 2.6% neurological complications.
Conclusions:
- The Rist catheter is a safe and effective device for diverse neurointerventional procedures.
- This system offers reduced conversion rates compared to previously reported data for TRA.

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
