Test ultrasound contrast to improve blood flow in legs
Part of Heart & circulation clinical trials.
This study checks whether using a special ultrasound with contrast can improve blood flow in people with peripheral artery disease (PAD). If you have leg circulation problems, it may help doctors measure and potentially enhance how well blood reaches your limb.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older
- If you have PAD, you have confirmed PAD in one or both legs and your symptom stage is 4 to 6
- You should not have major other illnesses that could affect blood flow in that limb
- You should not be pregnant or breastfeeding
- You cannot be allergic to ultrasound contrast material
- Your heart and circulation should be stable (not severely weak heart function, unstable blood pressure, or ongoing heart blood-flow problems)

Other trials that look related to this one.
This study uses ultrasound to measure blood flow in the legs of people with PAD symptoms and healthy volunteers. It aims to improve how doctors assess peripheral arterial disease without invasive tests.
This trial studies a specific ultrasound-based treatment aimed at improving healing of severe circulation-related ulcers in the legs. It may help if you have poor blood flow and a wound that hasn’t improved despite usual care.
This trial tests whether using a special ultrasound probe inside the artery (intravascular ultrasound) helps doctors better treat blocked leg arteries. It may lead to more effective procedures for patients with leg pain or wounds due to poor blood flow.
This study looks at how blood flows in the legs of people with peripheral artery disease (narrowed leg arteries) compared to healthy people. It uses CT scans to create 3D models, which may help doctors understand the disease better and could lead to better treatments.
This study tests a special camera (SnapshotNIR) that takes pictures of blood flow in your legs while you move them into different positions. It may help doctors better understand your circulation and diagnose peripheral artery disease (PAD) without needles or dye.
This trial uses a special CT scan (coronary CTA with HeartFlow analysis) to look for hidden blockages in the heart arteries of people who recently had a leg artery procedure. It may help detect heart problems early so they can be treated.
