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:

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Area of Science:

  • Neurosurgery
  • Interventional Radiology

Background:

  • The Rist guide catheter is designed for transradial neurointervention (TRN).
  • It has shown efficacy in accessing distal intracranial vessels.
  • High success rates have been reported with its use.

Purpose of the Study:

  • To investigate the impact of Rist guide catheter position on stability during TRN.
  • To correlate catheter position with effective catheter length (ECL).

Main Methods:

  • Retrospective study of 17 patients undergoing TRN with a 7-French Rist guide catheter.
  • Procedures included intracranial aneurysm and middle meningeal artery embolization.
  • Catheter stability assessed by position and ECL.

Main Results:

  • Stable positioning achieved in 13/17 cases at specific arterial segments (ICA, VA, ECA).
  • ECL correlated with stable positions: ~20 cm for petrous ICA, ~16 cm for VA/distal ECA.
  • All procedures were successful; one switch to femoral access, no access site complications.

Conclusions:

  • Rist catheter position is crucial for stability in TRN.
  • Understanding catheter behavior aids preprocedural planning and successful outcomes.
