Intravascular Ultrasound

What is Intravascular Ultrasound (IVUS)?

Intravascular Ultrasound (IVUS) is an advanced, catheter-based imaging technique that allows doctors to view detailed cross-sectional images of blood vessels from the inside. Unlike traditional ultrasound, which is performed from outside the body, IVUS uses a tiny ultrasound probe attached to a catheter inserted directly into the blood vessel.

This high-resolution technology helps assess arterial blockages, vessel size, plaque buildup, and overall vascular health with precision.

When is IVUS Used?

IVUS is most commonly used in patients with:

Peripheral Artery Disease (PAD)
Chronic leg pain or claudication
Non-healing ulcers or wounds on the feet/legs
Suspected arterial narrowing or blockages
Prior abnormal imaging (angiogram, CT, or Doppler studies)
Evaluation before or after stent placement or angioplasty

Why Choose IVUS Over Other Imaging?

IVUS provides real-time, high-definition imaging from inside the artery, offering several advantages:

More accurate measurement of vessel diameter and plaque size
Visual confirmation of blockages and stenosis severity
Helps guide stent placement and ensures complete opening of treated arteries
Identifies hidden or complex lesions that may be missed by traditional imaging

How the Procedure Works

A catheter with an ultrasound probe at its tip is inserted into the artery (usually in the leg or groin).
The catheter is guided through the blood vessel using X-ray or fluoroscopy.
The ultrasound probe rotates inside the artery, capturing real-time cross-sectional images.
The data is analyzed immediately to determine treatment options or confirm results of an intervention.

IVUS is often performed alongside a Lower Extremity Arteriogram or during an angioplasty or stent procedure.

Benefits of IVUS

Provides unmatched precision for diagnosis and treatment planning
Reduces the chance of under- or over-treatment
Can prevent complications by optimizing device placement
Painless and performed under local anesthesia with sedation
Allows personalized vascular care tailored to the patient’s exact anatomy

What to Expect

IVUS is typically done in a hospital or specialized vascular lab
Procedure time is usually 30–60 minutes
Most patients go home the same day after a short observation period
Walking and daily activities can resume within 24 hours in most cases

Risks and Safety

IVUS is considered very safe when performed by a trained vascular specialist. Potential (rare) risks may include:

Minor bleeding or bruising at the catheter insertion site
Temporary discomfort
Infection or allergic reaction (extremely rare)
