Official Title Prospective Single-Arm Safety Study of Cervical Lymphaticovenular Anastomosis (LVA) in Patients with Alzheimer's Disease Purpose of the Study Researchers are conducting this study to see if a minimally invasive microsurgery, called Cervical Lymphaticovenular Anastomosis (LVA), is safe for people with Alzheimer's Disease. How the Surgery Works Alzheimer's Disease is linked to the buildup of metabolic waste products (certain proteins) in the brain. Recent medical discoveries show that these wastes normally drain through small channels in the neck into the blood system. In this study, surgeons will use high-powered microscopes to connect these drainage channels (lymphatic vessels) in the neck directly to small nearby veins. The goal is to create a "detour" that helps the brain clear out these harmful proteins more effectively. What to Expect Safety First: The main goal is to find out if the surgery is safe and well-tolerated by patients. The Procedure: The surgery is performed under general anesthesia and typically takes 4 to 6 hours. It involves small (about 5 cm) incisions on both sides of the neck. Follow-up: Participants will be monitored for at least 12 months. Researchers will use memory tests, brain scans (MRI and PET), and blood tests to see if the surgery helps with daily activities or slows down memory loss.
