Jugular venous reflux could influence cerebral blood flow and neurological disease
May 13, 2011 at 8:18am
Anyone who has been following this page for awhile knows about the research in Taiwan by Dr. Chung and his associates into jugular valve insufficiency and transient global amnesia. I wrote to Dr. Chung in '09 and sent him all of Dr. Zamboni's research, noting that I thought he would find some interesting and complimentary discoveries to his own research on the jugular veins.
Dr. Chung and his associates are different in their studies, in that they employ valsalva manuever (exerting pressure against a closed airway-- which happens during straining, sneezing, breath-holding, etc) in order to create jugular reflux, and as we all know, Dr. Zamboni finds reflux in those with CCSVI during normal breathing.
It appears Dr. Chung's team is now looking at CCSVI. We can only hope they bring further understanding into how jugular venous reflux affects cerebral blood flow and perfusion---

- Abstract
Usually, disturbance of arterial blood supply and circulation of cerebrospinal fluid are considered more clinically relevant, though accumulating data suggest that cerebral venous insufficiency does have important pathophysiological consequences in various neurological diseases(1-5). Hindrance of principal and collateral cerebral venous outflow will cause elevation of venous pressure, insufficiency of cerebral blood flow (CBF), increase of intracranial pressure, and eventually lead to parenchymal abnormalities. Disorders involving cerebral venous circulation, such as cerebral sinus thrombosis, dural arteriovenous fistula, and surgical sacrifice of the cerebral veins, may lead to serious complications. However, most physicians do not assign practical importance to cerebral venous circulation.
