The slowing of blood flow in the vertebral artery may lead to cerebral ischemia. The vertebral artery supplies brain tissue such as the cerebellum, so patients may experience symptoms of cerebellar ischemia, such as dizziness and tinnitus; in severe cases, this may lead to ataxia, so patients may exhibit poor coordination of the extremities and changes in gait. Patients with slowed blood flow in the vertebral artery should be further examined to determine the cause, especially pay attention to the formation of thrombus in the wall of the vertebral artery and the possibility of arterial plaque dislodgement, which should be given high priority and can take vasodilators and plaque stabilizers. If there are elevated blood lipids and blood sugar, it is also important to control your blood sugar and blood lipids as well as blood pressure control.
