Transradial Approach

Transradial approach is a catheterization or interventional procedure performed via the radial artery in the cath lab or interventional radiology. Over the past few years this approach has become more popular. Transradial procedure is associated with fewer bleeding complications, shorter post-procedure recovery and earlier discharge when compared to the traditional femoral approach to cardiac catheterization.

Basic equipment:

1) Low pressure contrast injection lines

2) Sterile disposable towels

3) Steri-Drape; Small drape with adhesive aperture, 22’ x 25”;

4) 20G 1-3/4” Jelco Angiocath needle, or, 21g X 1” thin wall needle

5) Guide wires 035” x145cm Hydrophilic guidewire

a. Long , Angled– for Catheter exchange

b. J-tip –For navigating through a long radial bridge and normal anatomy

c. Stiff – For navigating through tortuous anatomy

6) 5 & 6 Fr 10 cm hydrophilic introducer sheaths with 0.021 guidewire

a. Features to consider when selecting an arterial sheath are length, tapering at the tip, a smooth transition and the presence of hydrophilic coating

7) Coronary Wires 0.014

8) 4,5 and 6 Fr Catheters

9) Radial flush cocktail; Example of drug doses utilized

a. 2500 heparin: 1000/mL (2.5mL)

b. 2.5mg Verapamil; 2.5mg/mL (1mL)
