Congenital arteriovenous fistula

This study compares two common ways to access the blood for dialysis: a tunneled catheter (a tube placed in a large vein) versus a surgically created fistula (connecting an artery to a vein). The trial will enroll 220 patients aged 60 or older (or younger but with multiple health…

This early study tests a new ultra-high-pressure balloon designed to widen narrowed blood vessels in people on dialysis. About 35 participants will receive the balloon treatment to see if it safely restores blood flow and improves dialysis access. The goal is to fix the narrowing…

This study tests a special coil device designed to block abnormal blood vessels in the arms or legs. The device is inserted through a small tube and placed into the target vessel to stop blood flow. About 139 people with conditions like bleeding, malformed vessels, or aneurysms w…

People on hemodialysis must closely manage fluid, diet, and their vascular access between sessions, and sticking to these routines is hard. Researchers at the University of Rome Tor Vergata built DialysisBot, an AI chatbot that answers patient questions using only a hospital-appr…

This study tests whether a 4-7-8 breathing exercise can reduce pain when needles are inserted into the arm for hemodialysis. About 80 adults on dialysis will either learn the breathing technique or receive standard care. The goal is to see if this easy, drug-free method makes the…

Researchers at Assiut University Hospital survey adults with advanced chronic kidney disease about arteriovenous fistula creation, the surgically connected vein and artery used for hemodialysis. The study includes pre-dialysis patients and people already on maintenance hemodialys…

This early study tests a wearable device that listens to the sound of blood flow in the arm of people on dialysis. The goal is to see if the device can accurately measure the same signals as a standard stethoscope. Six adults with mature fistulas will wear the device weekly for 8…
