Limb ischemia

Researchers are testing whether seltoplasmid, a gene therapy injected into the calf muscle, can improve outcomes for people with type 2 diabetes who have poor blood flow to the foot and a non-healing ulcer. All participants first undergo a standard procedure to restore blood flow…

This study compares two ways to guide a minimally invasive procedure that opens blocked arteries below the knee in people with chronic limb-threatening ischemia, a severe form of peripheral artery disease. One group receives standard X-ray guidance (angiography) alone; the other …

This Europe-wide study will follow 400 people with severe leg artery disease (chronic limb-threatening ischemia) to see if a new dissolvable, drug-coated scaffold can keep leg arteries open better than standard treatments. The scaffold releases medication to prevent re-blockage a…

This study will follow 250 people with chronic limb-threatening ischemia (CLTI) across Europe to see how well orbital atherectomy works in real life. The procedure uses a tiny spinning tool to gently remove hard calcium from leg arteries, making it easier for balloons or stents t…

This phase 1/2 trial tests whether a patient's own stem cells, taken from belly fat and grown in a lab, can heal leg ulcers caused by severe peripheral artery disease. 40 participants will either receive stem cell injections and a special cell-containing dressing, or standard hyd…

This study tests a procedure called woundsome revascularization in 50 people with chronic limb-threatening ischemia (CLTI), the most severe form of peripheral artery disease. Doctors use balloon angioplasty to open blocked arteries that supply blood directly to the wound area. Th…

This study tests whether routinely placing a small tube in the leg artery (distal perfusion catheter) is better than waiting until a problem arises in patients on mechanical heart pumps. About 500 adults with severe heart failure or shock will be randomly assigned to one of the t…

This trial tests whether using a laser device (Auryon Atherectomy System) along with standard balloon angioplasty is safer and more effective than balloon angioplasty alone for treating severe blockages in the lower leg arteries. The study will enroll 50 people with critical limb…

This study tests if a special balloon called the Chocolate PTA balloon prepares leg arteries better than a standard balloon before using a drug-coated balloon to treat blockages. About 242 adults with peripheral artery disease will take part. The goal is to see if the Chocolate b…

This trial compares a new drug-coated temporary stent to standard balloon angioplasty for treating critical limb ischemia, a severe form of peripheral artery disease that can lead to amputation. The stent delivers sirolimus to prevent re-narrowing and is removed after treatment. …

This study investigates whether a device called FREMS, which delivers rhythmic electrical pulses to the legs, can improve blood flow, reduce nerve pain and numbness, and enhance quality of life in people with type 2 diabetes who have peripheral neuropathy and poor leg circulation…

This observational study tests a spectroscopic sensor that measures oxygen levels in muscle tissue during vascular surgery. It aims to see if the sensor can detect changes in oxygenation when blood flow is temporarily blocked and then restored. The study involves 30 adults underg…

This observational study tests a new sensor that measures oxygen levels in tissue flaps during reconstructive surgery. The sensor is placed in the flap and tracks oxygen saturation continuously, comparing it to blood samples and key surgical events. The goal is to see if this tec…

This study looks at how anxiety and depression influence shared decision-making in patients aged 65 and older with critical limb threatening ischaemia (CLTI), a severe form of leg artery disease. Researchers will interview patients, their carers, and healthcare staff to understan…

This observational study will examine whether a protein called the GLP-1 receptor is more active in patients with severe leg artery disease compared to those with milder symptoms. Researchers will take one extra blood sample from 50 adults with peripheral artery disease to measur…
