Elie Dolgin in Nature:
The video opens with a man in his 80s slumped in a hospital bed, his face hollow as he scrunches his eyes. A jump cut advances the scene three days: the man is alert now, words gathering as he identifies his son. Six months later, he is pictured sitting upright, engaged in conversation. His gaze is animated. At eight months, the man walks briskly down a hospital corridor. He recites a near-century-old Maoist military anthem from memory. He is practically unrecognizable from the withered figure in the opening frame.
The footage records the recovery of a man who, in September 2020, became the first person in the world to undergo a surgery known as deep cervical lymphatic-venous anastomosis (dcLVA) to treat Alzheimer’s disease. The procedure involves connecting tiny lymphatic vessels in the neck — part of the drainage system that carries waste away from the brain — to nearby veins, creating a route that, in theory, allows fluid and waste proteins to flow more easily into the bloodstream. The treatment was first reported1 in 2022 in a Chinese-language journal by microsurgeon Qingping Xie, president of the Qiushi Hospital in Hangzhou, China. At the time, it drew little notice. But that changed the following year, when Wei Chen, a lymphatic microsurgeon at the Cleveland Clinic in Ohio, began showing the footage (with consent from Xie and the man’s family) at surgical meetings around the world. “A lot of jaws dropped,” recalls Chen. “It basically started a frenzy of this surgery being performed left and right.”
