Overview
The data that had been published up till now entails an incidence of about 2% to 34% of radial artery spasm, which would result in transfemoral approach being used instead. [1]. So some precautions should be made beforehand in anticipation of such complications.
Potential Pitfalls of the Radial Approach to Cardiac Catheterization
1- Radial artery spasm:-
- In order to decrease the incidence of radial artery spasm, some interventionist tend to give light sedation as well as intra-arterial Nitroglycerin and calcium channel blocker (verapamil or diltiazem) in order to relax the smooth muscles of the radial artery.
2- Vessel tortuosity. Some of the tortuous forms are:-
- Alpha shape radial artery.
- S-shaped radial artery.
- Proximal and distal omega shaped radial artery.
- Brachial alpha loop.
- High origin radial artery.
3- Guide catheter support and selection may be reduced.
4- Loss of radial artery pulse in 4% of cases.
5- Potential increase in the duration of the procedure and fluroscopy time
6- The radial artery has been instrumented should there be a desire to use it as a conduit for CABG
7- It is the second and not the first approach learned by trainees
8- There is a learning curve in treating spasm, navigating anatomy, and manipulating catheters
9- Anatomically there can be a loop in the artery near the brachial in about 10% of cases
10- Smaller sheaths are required (4-8F)
