TRANSRADIAL CATHETERIZATION:
New Procedure for Patients Undergoing Cardiac Catheterization
What Is Cardiac Catheterization?
Over two million coronary angiography diagnostic procedures are performed
annually in the United States. Contrast dye media is injected into the coronary arteries
of the heart via a catheter (tube) usually threaded into an artery in the groin area. This
is the transfemoral approach. The procedure assists cardiologists in imaging diseased
arteries that may be blocked due to build-up of fatty cholesterol deposits; and then, to
use various procedures and methods to reduce the blockage.
The New Technique & Its Advantages
Improvement and miniaturization of catheter equipment now allows the radial
artery (patients wrist) to be used for coronary investigation and intervention
(Schneider/Namic). It is called the transradial approach. This is a new procedure in the
United States, though it is already routinely used in some hospitals in Europe and Canada.
The advantages of the new procedure include:
Easier access to the artery due to its
superficial location in the wrist. This may be the only access for patients
suffering from severe peripheral vascular disease, obesity or compromised femoral
arteries.
The superficial location and smaller vessel
size allow for better hemostasis (control of bleeding) once the procedure is completed, in
comparison to the femoral artery in the groin. Significantly less entry site bleeding
complications result from using the transradial approach.
Lack of important structures close to the
radial artery, a good collateral ulnar artery circulation and its superficial position
also contribute to a low complication rate.
No flat on the back bed rest!
Less complications translate into less nursing time required, especially during the first
two hours after the procedure; less intensity of care; shorter length of stay; and lowered
hospital costs - a potential cost savings of $1,600 to $2,300. Typically, with a
transfemoral approach, six hours of complete bed rest are required for complete stoppage
of bleeding after the groin puncture. Patients must lie completely still during this time
with a weight on the groin area to stop the bleeding. This is inconvenient and especially
uncomfortable for patients with back problems. With the transradial approach, patients may
generally move about within a short time after the procedure and usually leave the
hospital the same day, which may result in lower hospital costs.

Robert M. Siegel, M.D., Medical
Director of Advanced Cardiac Specialists, performed one of the first transradial
catheterization procedures in the Valley at our cardiac catheterization lab
then housed at Phoenix
Memorial Hospital.
While the new technology is not available for
all patients, for those who do qualify, there is a high degree of success and a lower
complication rate, resulting in early mobilization and discharge.
