Deep Cervical Lymphatlc-Venous Anastomosis Surgery for the Treatment of Alzheimer's Disease: A Pilot Study (DIVA Study)

This trial tests whether a surgical procedure called deep cervical lymphatic-venous anastomosis (dcLVA) — which aims to improve fluid drainage from the brain — can slow Alzheimer's progression when added to standard medication, including the drug lecanemab. Researchers will measure changes in a standard dementia rating scale over 12 months. It is a Phase 3 pilot study, meaning it is testing effectiveness at meaningful scale, though labeled a pilot suggesting relatively small numbers.
