via CCSVI in Multiple Sclerosis - "From Dr. B.B. Lee, the leading expert in vascular malformations, a review of Venous Embryology and how CCSVI begins-
Vascular anomalies are relatively rare and difficult to understand and interpret. Yet, venous embryology is one of the most neglected areas of basic science in medicine despite its critical ability to explain the many obscure conditions related to anomalous anatomy (eg, membranous occlusion of suprahepatic inferior vena cava as a cause of primary Budd-Chiari Syndrome).1,2

Such venous anomalies are a result of the defective development of embryonic veins during the vascular trunk formation period in the later stage of embryonic development.3,4 A benign narrowing (stenosis) of the jugular-azygos vein system is a good example of how defective development can cause a unique condition, in this case chronic cerebrospinal venous insufficiency (CCSVI).5,6" https://www.facebook.com/permalink.php?story_fbid=595194513830991&id=110796282297
