CRITICAL LIMB ISCHEMIA

This pilot study tests whether giving special nutritional shakes before and after surgery can improve the health of patients with critical limb ischemia, a severe form of peripheral artery disease. About 30 participants will drink the shakes for one to two weeks before and after …

This study is testing a device called the LimFlow Stent Graft System for people with late-stage chronic limb-threatening ischemia, a severe form of peripheral artery disease where blood flow to the leg is critically low. The device creates a new connection between a vein and arte…

This study tests whether a laser device called the Auryon Atherectomy System, used with standard balloon angioplasty, works better than balloon angioplasty alone for people with severe leg artery blockages (critical limb ischemia). The trial will enroll 224 adults who are at risk…

This study is testing a device that uses sound waves to break up calcium buildup in the leg arteries of people with peripheral artery disease. The goal is to improve blood flow, reduce pain, and help people walk better. About 50 participants will be followed for one year to see i…

This study tests whether injecting donor stem cells (Stempeucel) into the leg muscle can help people with critical limb ischemia, a severe form of peripheral artery disease. Ten Malaysian patients who cannot have surgery or angioplasty will receive the stem cells and be followed …

This study is testing whether injections of Stempeucel, a stem cell product made from donor bone marrow, can help people with critical limb ischemia caused by Buerger's disease. The goal is to see if it reduces pain, heals ulcers, improves blood flow, and prevents amputation. Onl…

This study is testing whether a quick ultrasound measurement of blood flow in the foot (called systolic rise time) can predict major limb events like amputation or severe ischemia in people with critical limb ischemia. Researchers will follow 134 patients for 6 months after surge…

This study tests whether a new type of PET/MR scan using a tracer called FAZA can measure oxygen levels in leg tissues of people with critical limb ischemia, a severe form of peripheral artery disease. About 40 adults who are scheduled for a procedure to restore blood flow will g…

This study looks at immune cells called macrophages in the arteries of people with heart disease or poor leg circulation. Researchers will use imaging and blood tests to see how these cells are activated. The goal is to better understand the disease, not to test a new treatment. …
