The backup of blood flow could have caused a stroke or hemorrhage, according to Greenwald.
“Imagine this vein, where all the cerebral spinal fluid inside the head and spine no longer flows through this area,” he said. “You get a big back up and that itself could cause a stroke. In the long-term … the venous system can’t get the blood out of the brain. It’s like a Lincoln Tunnel back up.”
