Here are some common terms in the CCSVI handbook. Please PM me if there are additional terms you think we should add, or better definitions, and I'll update-
agenesis a type of narrowing (stenosis) of the vein seen by Dr. Zamboni - Absence, failure of formation, or imperfect development of any part.
annulus a type of narrowing (stenosis) of the vein seen by Dr. Zamboni- A ring, a circular or ring shaped structure, as in a ring shaped stricture of a vein
atresia a type of narrowing (stenosis) of the vein seen by Dr. Zamboni - Absence of a normal opening or normally patent lumen
Azygos vein - This is the vein which shows blockage in 86% of MS patients tested by Dr Zamboni. The vein running up the right side of the thoracic vertebral column of the spine. Takes deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava vein. It is called azygos, because it doesn’t have a partner vein on the left side of the body...it is unpaired.
CCSVI- Chronic Cerebrospinal Venous Insufficiency The medical condition termed by Dr. Paulo Zamboni. A condition where deoxyginated bloodflow from the veins surrounding the brain and spine is slowed or blocked in its return to the heart. This condition arises from blockage in the internal jugular and/or azygos veins. The Cerebrospinal system is the brain and spine. (Chronic venous insufficiency or CVI is a medical term referring to blockage in return of blood from the legs to the heart.)
endovascular procedure - originally designed as a way to diagnose problems in blood vessels -it is a minimally invasive surgical procedure used to place the stents in the veins. A catheter is injected into a major vein near the groin, using dye, it can be seen on live x-ray as it travels up the body.
internal jugular veins - Dr. Zamboni found stenosis here in 91% of the MS patients he tested. These major veins collect blood from the brain, the outside of the face and the neck. They run down the inside of the neck -outside the internal and common carotid arteries and unite with the subclavian vein to form the innominate vein.
interventional radiologist -a subspecialty of radiology in which minimally invasive procedures are performed using image guidance. Some of these procedures are done for purely diagnostic purposes while others are done for treatment purposes (e.g., stent placement). Pictures are used to direct these procedures, which are usually done with needles or other tiny instruments like small tubes called catheters. The images provide road maps that allow the Interventional Radiologist to guide these instruments through the body to the areas of interest.
Magnetic resonance venography
The type of magnetic resonance imaging (MRI) used to visualize veins. The MRV uses the same machine as an MRI, but a special computer software allows it to only extract generated-by-blood images, as it flows through the veins. These images give doctors a rough idea of whether blood flow through a vein of interest is affected by blood clots or other disease processes
patency -degree of openness and lack of obstruction- this term is used in relation to stents and the percentage of blood flow allowed through a stented vein.
reflux - the backing up of blood into brain and spine, caused by blockage in the veins
septum a type of stenosis of the vein seen by Dr. Zamboni - A thin wall dividing two cavities or masses of softer tissue
stenosis - literally means “narrowing.” A blockage in veins caused by an abnormal narrowing of the vein itself.
stent - a man-made 'tube' constructed of mesh metal, inserted into the vein to prevent, or counteract, a localized flow constriction.
vein- the blood vessel that carries deoxyginated blood back to the heart
venography (also called phlebography) is a procedure in which an x-ray of the veins, a venogram, is taken after a special dye is injected into the veins.
