What is LVA Surgery?.

Advanced Microsurgical Technique

Deep Cervical Lymphaticovenous Anastomosis (LVA) is an avant-garde surgical methodology conceived by Professor Qingping Xie of Hangzhou Qiushi Hospital. Its pioneering objective is the establishment of a tangible conduit that expedites the removal of toxic proteins, effectively expelling protein accumulations from the brain. The breakthrough point for his method is the fact that the surgical site is on the side of the neck area which is extracranial (outside skull), which provides a significant control over the safety of the procedure and is considered a much less invasive method. According to the anatomy of the lymphatic’s distribution, the first exit of brain lymphatic vessel happens at V subdivision on the neck.

The impairment of this circulation system might lead to the accumulation of substances like tau proteins within brain tissue regions. The neurotoxicity of these proteins can cause synaptic damage and neuronal cell death, contributing to the onset of Alzheimer's disease.

State-of-the-art microsurgical equipment to be used in LVA procedures in the near future

Using state of the art microsurgical techniques, we create precise connections between lymphatic vessels and veins in the deep cervical region. This innovative procedure helps improve cerebral fluid drainage and has shown promising results in slowing AD progression. To do this, we will use precise machine-controlled microsurgical instruments and a microscope to perform the surgery in the near future.
