Chronic Cerebrospinal Venous Insufficiency (CCSVI)
The Toronto Centre for Medical Imaging clinic is pleased to advise that we now have technologists that are trained and certified in “Echo-Doppler in the diagnosis of Chronic Cerebrospinal Venous Insufficiency (CCSVI).”
Our laboratory now offers testing for CCSVI. A referral from a physician is required. Please be advised that there is a $250 fee for this test which is not currently covered by OHIP.
Our technician and Radiologist (Dr. Ismail) were trained at Barrie Vascular Imaging. Dr. Sandy McDonald and his technologists (from Barrie) have been trained in Italy by Dr. Zamboni.
Please note that ultrasound testing of the neck veins assesses for indirect evidence of cerebral venous outflow obstruction. The exact site of the obstruction is usually difficult to demonstrate with sonography of the neck veins. Further testing to localize the actual site of narrowing/obstruction based on Dr. Zamboni’s finding would include venography and/or MRI. It should be remembered that Dr. Zamboni’s hypothesis is still highly controversial within the medical community and decision to proceed with more invasive testing such as venography ought to take this into consideration.
