Basilar artery blood flow is increasing. What's going on?

The increased blood flow velocity of basilar artery indicates brain insufficiency. It is considered to be related to factors such as insufficient blood supply to brain, cerebral vasospasm, cerebral vascular stenosis, etc. When blood flows in blood vessels, the smaller the cross section of blood vessels, the faster the blood flow velocity. It is recommended to go to hospital for TCD, CT, MRI, angiography and other examinations.
