United Hospital System is a leader in cardiovascular care. We provide the latest tests and procedures to diagnose and treat heart and vascular conditions.
Orthopedic care you can count on from a team you can trust
To view the inner lining of the coronary (heart) or peripheral vascular (e.g. lower abdomen, kidneys, arms, legs) arteries. Intravascular ultrasound allows detailed evaluation of plaque (atherosclerosis)--its distribution, location, size, effect on blood vessel diameter--that may be lining the inside of your arteries. This information is used to evaluate cardiovascular disease which assists in determining the next step in treatment if needed (i.e. angioplasty or bypass surgery).
Intravascular ultrasound (IVUS) is an invasive diagnostic test using a catheter with a sound transducer (or sound probe) on the end. It is usually performed in conjunction with angiography/catheterization and/or transcatheter interventions (e.g. PTCA, stent, etc.) The catheter is threaded thru the artery in the groin to a specific location of the arterial system to further diagnose the extent of disease. High-frequency sound waves are used to create precise images of the inner arterial walls. These images are displayed in streaming video on a monitor. Once the diagnosis is made, the catheter with the ultrasound tip attached is carefully removed, and then pressure is applied over the groin area to stop any bleeding.
