Chronic cerebrospinal venous insufficiency (CCSVI)
We are pleased to offer patients with multiple sclerosis or conditions with similar neurological symptoms, non-invasive ultrasound assessment of their jugular and vertebral veins to diagnose the presence of chronic cerebrospinal venous insufficiency (CCSVI). Patients require a referral from their GP or neurologist specifically requesting this ultrasound service.
The hypothesis is that various abnormalities of these vessels do not allow normal blood flow. These include circumferential stenosis of the whole vessel wall, congenital webs, valve malformation, vessel hypoplasia, vessel twisting, vessel agenesis and external vessel compression. The resulting increased pressure of blood in the brain and spinal cord allows for the deposition of iron deposits that may trigger local inflammation, brain cell injury and death, in a similar way to the damage that is seen with the development of venous ulcers in the lower legs associated with long-standing varicose veins.
