Summary

The goal of this clinical trial is to explore the safety and efficacy of Lymphaticovenous Anastomosis (LVA) for the Treatment of Alzheimer's Disease (AD). The main questions it aims to answer are:

1. After LVA surgery treatment, do patients with AD show improvement in dementia, cognitive impairment, neurobehavioral symptoms?
2. What are the complications associated with LVA treatment for AD, including perioperative complications and long-term complications?
3. What is the mechanism of LVA treatment for AD patients, and what changes occur in AD-related biomarkers (Aβ42、 Aβ40、Aβ42/40、pTau217、pTau181) before and after surgery?

Conditions

  • Alzheimer&Amp;#39;s Disease (AD)

Interventions

PROCEDURE

Lymphaticovenous Anastomosis

The basic principle of LVA surgery is to anastomose the deep cervical lymphatic vessels of the brain with adjacent small veins, effectively enabling the direct reflow of accumulated Aβ and tau proteins in the brain's lymphatic circulation into the venous system, thereby improving the symptoms of Alzheimer's Disease (AD).
