CCSVI is a term used to describe the compromise of blood flow in veins draining the CNS. Failure to treat the condition can, in the long run, predispose one to multiple sclerosis. It is commonly diagnosed using a Trans-cranial Doppler ultrasound, an MRI scan or Doppler sonography. It can be managed by a surgical procedure known as venous angioplasty where a surgeon will insert a balloon to keep veins open, clear a blockage & restore blood flow to spinal cord and brain.
