Road map vs. ultrasound for retrograde leg angioplasty
Part of Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are an adult (18 or older).
- You have critical limb-threatening ischemia (CLTI) with significant blockages in the femoropopliteal arteries.
- You have Rutherford class 5, meaning non-healing wounds or ulcers on your leg or foot.
- Your doctor was unable to access the blocked artery from the groin (antegrade approach) or it failed.
- You need a retrograde puncture (from the ankle area) as part of your angioplasty or stent procedure.
- You do not have an active infection at the planned puncture site (ankle).
- You do not have severe artery calcification or major anatomical issues that would make the puncture unsafe.

Other trials that look related to this one.
This trial tests a laser device (Auryon) to clear blockages in leg arteries below the knee, compared to standard balloon angioplasty. It aims to improve blood flow and save the leg from amputation in people with severe peripheral artery disease.
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 trial tests a special balloon that releases medication to help keep leg arteries open. It's for people with narrowed or blocked arteries in the leg, either above or below the knee.
This study tests a new way to restore blood flow to the leg in people who have wounds or dead tissue on their foot and have run out of other treatment options. It's for those who have already tried angioplasty twice without success or have severely hardened small arteries.
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.
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.
