Deep Cervical Lymphatic Venous Anastomosis in the Treatment of Alzheimer's Disease (CLEAN-AD Registry)

The intervention requires to perform bilateral deep cervical lymphatic venous anastomosis (DC-LVA). Through cervical incision, the deep cervical lymphatic tissue is anatomically dissected and anastomosed with the venous system of the neck. Under indocyanine green (ICG) navigation, the flow of lymphatic fluid into the vein could be observed via ICG tracing fluorescence after surgery.
