Ultrasound vs. X-ray for severe leg artery disease
Part of Blood & lymphatic, Heart & circulation clinical trials.
This trial compares a non-invasive ultrasound test to a standard X-ray angiography for evaluating severe blockages in leg arteries that cause pain, ulcers, or tissue damage. It aims to see if ultrasound alone can guide treatment decisions safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been diagnosed with a severe lack of blood flow to your leg that causes pain at rest, a non-healing sore, or dead tissue (gangrene).
- You are healthy enough to undergo X-ray angiography if needed.
- You are not allergic to contrast dye used in X-rays and your kidneys work well enough for it.
- You do not have artery disease caused by inflammation (vasculitis) or Buerger's disease.
- You can have a complete ultrasound exam of your leg arteries.

This trial compares two imaging methods (road map vs. ultrasound) to guide a needle puncture from the ankle area during angioplasty for blocked leg arteries. It aims to see which method is safer and more effective for patients with severe leg wounds or ulcers that need this retrograde approach.
This trial tests a new way to open blocked arteries below the knee in people with severe leg wounds due to poor blood flow (chronic limb-threatening ischemia). The goal is to help wounds heal and save the leg from amputation.
This trial tests whether using a special ultrasound probe inside the artery (called intravascular ultrasound) helps guide treatment for people with severe leg artery blockages that cause pain, wounds, or gangrene. The goal is to see if it improves blood flow and saves the leg.
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 tests if using a special ultrasound camera inside the blood vessels helps doctors treat blockages below the knee in people with severe leg pain, sores, or gangrene due to poor blood flow.
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.
