What is coronary IVUS?
Intravascular Ultrasound (IVUS) is a catheter-based diagnostic procedure used to view the inside of a coronary artery, providing a real-time view.
What is IVUS pullback?
The Attribute IVUS Pullback Rate (0018,3101) specifies the constant velocity of longitudinal movement of the Intravascular imaging catheter. Positive values indicate movement from Distal to Proximal (pulling back). Negative values indicate movement from Proximal to Distal (pushing forward).
What is a Venogram with IVUS?
A venogram is a procedure to make the veins visible for the doctor to see blood flow. Venograms are used to diagnose and determine treatment options for a number of vascular diseases including but not limited to Deep Vein Thrombosis and Ilac Vein Compression.
How do you use IVUS machine?
To use IVUS, physicians use a guide wire, usually 0.36 mm, and the IVUS-tipped catheter is then fed over the guide wire. Angiography is used to guide the IVUS catheter to the area of the vessel to be imaged. It is placed farthest away from the area to be imaged and is then pulled back through the area of stenosis.
How do you interpret IVUS?
The interpretation of IVUS relies on simple visual inspection of acoustic reflections to determine plaque composition. However, different tissue components may look quite similar, and artifacts may adversely affect ultrasound images. IVUS commonly detects occult disease in angiographically “normal” sites.
Why is IVUS used?
Doctors use IVUS to assist in the diagnosis and treatment of both arteries and veins. In the veins, doctors most often IVUS for acute and chronic blood clots, especially if narrowing of the veins is thought to be the cause. IVUS can help find areas of narrowing or blockage deep in the body.
How much does IVUS cost?
The disposable IVUS catheters cost about $600-$1,000 each. To use IVUS, physicians use a guide wire, usually 0.36 mm, and the IVUS-tipped catheter is then fed over the guide wire. Angiography is used to guide the IVUS catheter to the area of the vessel to be imaged.
Can you walk after a venogram?
You may walk and climb steps so long as you do not have excessive bruising, swelling or pain at the puncture site. You may resume driving the next day after the procedure. You will be discharged with a dressing over the puncture site.
How long does a venography take?
A venogram takes between 30 and 90 minutes to perform. Fluids will be run through your IV to remove the contrast material from your veins. You will also be instructed to drink a lot of fluids for the next day.
How do you use IVUS?
What is the difference between IVUS and OCT?
IVUS uses ultrasound (∼40-μm wavelength at 40 MHz), whereas OCT uses infrared light (1.3-μm wavelength), which confers significantly greater resolution but has lower tissue penetration.
