Blood flow study for leg artery disease
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be 18 years or older.
- You must have already had a CT scan (called CTA) of your legs.
- For the PAD group: you have been diagnosed with peripheral artery disease, usually with a test called ABI showing 0.90 or less, or a CT or ultrasound showing a blocked or narrowed artery.
- For the healthy group: you have no symptoms of leg pain from poor circulation and no signs of narrowed leg arteries on your CT scan.
- You cannot have had prior surgery or procedures to open your leg arteries.
- Your CT scan quality must be good enough for 3D reconstruction.

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 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.
This study looks for markers in the blood of people with peripheral arterial disease (PAD), a condition where leg arteries narrow and reduce blood flow. It aims to better understand the disease and improve future diagnosis and treatment.
This study looks at how well blood flows through leg arteries after using a balloon to open blockages. It uses special measurements to check if the treatment fully restores blood flow, which may help guide future treatments.
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.
This study tests a special catheter to open blocked arteries in the thigh, knee, or lower leg. It may help improve blood flow and reduce symptoms like leg pain or wounds.
