Steps in the Transradial Catheterization Procedure

Before the transradial catheterization procedure begins, a numbing medicine is injected into the wrist at the catheter-insertion site. A local anesthetic is used during the procedure to reduce discomfort while allowing you to stay awake. You may be given a mild sedative to help you relax.

A tiny guidewire is inserted into the artery and guided to the desired position in the heart, great vessels, or coronary arteries. The location of the guidewire and, later, the catheter is monitored on a fluoroscope, a special viewing camera that is also used to take x-ray images as the procedures are carried out. After the catheterization procedure, the insertion site is treated with pressure to stop any bleeding, which is usually minimal. Recovery time is only about 20 minutes, and you may be able to leave the hospital within about one hour.

There are specific procedures that can be performed using the transradial access site, including angiographic procedures and angioplasty:

• Cardiac Catheterization

• Coronary Artery Balloon Angioplasty
