Visualization of the perivenous glymphatic efflux in human brain after laser interstitial thermal therapy

Recent studies have revealed that there is existence of a specific waste clearance pathway in the brain, coined the glymphatic system. This case report demonstrates supportive finding of drainage of Gadolinium and waste products released after Laser Interstitial Thermal Therapy via perivenous routes and a paradural lymphatic system. These findings provide further evidence of interstitial fluid drainage along the perivenous spaces in accordance with a glymphatic system theory.
