Brief Summary

This is an imaging investigation to assess the factors effecting radial artery diameter:

• Patient demographics
• Diameter change post standard care preparation

Conditions

Radiology, Interventional

Keywords

specialty; RADIOGRAPHY, INTERVENTIONAL is available for the diagnostic and therapeutic procedures

Outcome Measures

Primary Outcomes (1)

• Radial Artery diameter

  The change in RA diameter during a standard of care RA access procedure performed by an interventional Radiologist before the procedure, during the procedure and immediately after the procedure and how this compares to patient demographics.

  Before the procedure, during the procedure, and immediately after the procedure

Study Arms (1)

All patients

All patients undergoing Radial Artery Access requiring interventional radiology.

Procedure: Radial Artery Access

Interventions

Radial Artery Access PROCEDURE

The radial artery is stabilized between the thumb and forefinger of the left hand and 1 to 2 mL of subcutaneous lidocaine is used to create a wheal over the zone of planned entry.

All patients
