Authorities ban use of LVA surgery to treat Alzheimer's

China's top health authority has banned the use of a minimally invasive surgical procedure to treat Alzheimer's disease.

The procedure, which is still undergoing clinical research, connects neck lymphatic vessels to adjacent veins to enhance the brain's lymphatic clearance system.

The National Health Commission said, in a notice released on Tuesday, it has recently learned that some medical institutions are conducting lymphaticovenous anastomosis, also known as LVA surgery, on patients diagnosed with Alzheimer's disease. Following the commission's discovery, it conducted assessments on the procedure's safety and efficacy.
