Ultrasound versus X-ray dye test for severe leg pain
Part of Heart & circulation clinical trials.
This study compares two ways to look at the blood vessels in your legs: a safe, painless ultrasound and an angiography (X-ray with dye). The goal is to see which method works better for evaluating blocked arteries that cause severe leg pain or wounds, so you can get the right treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have severe pain in your foot or leg even when resting, a sore that hasn't healed, or dead tissue (gangrene) in your leg or foot.
- You are healthy enough to have an angiography (X-ray with dye to see your blood vessels).
- You are not allergic to the contrast dye used in angiography, and your kidneys are working well enough to safely use it.
- Your leg artery problems are caused by hardening of the arteries (not by inflammation, Buerger's disease, or other rare conditions).
- You are able to have an ultrasound of your legs (a painless test using sound waves).

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 study tests a new way to restore blood flow in the lower leg for people with chronic limb-threatening ischemia, a serious condition where leg wounds won't heal due to poor circulation. If it works, this treatment could help save the leg and avoid amputation.
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 trial tests whether using a special ultrasound probe inside the arteries (called IVUS) during a procedure to open blocked vessels below the knee can improve outcomes for patients with critical limb ischemia — a serious lack of blood flow that causes pain, sores, or gangrene. If you qualify, the procedure may help heal your wounds and relieve pain.
This study tests whether using a special ultrasound probe inside the artery during a leg procedure helps doctors open blockages more safely and effectively. It aims to improve blood flow and save the leg for people with severe peripheral artery disease who have pain, wounds, or gangrene.
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.
