Vertebrobasilar circulatory disorders
Vertebrobasilar circulatory disorders are conditions in which blood supply to the back of the brain is disrupted.
Vertebrobasilar insufficiency; Posterior circulation ischemia; Beauty parlor syndrome; TIA - vertebrobasilar insufficiency; Dizziness - vertebrobasilar insufficiency; Vertigo - vertebrobasilar insufficiency
Two vertebral arteries join to form the basilar artery. These are the main blood vessels that provide blood flow to the back of the brain.
The areas in the back of the brain that receive blood from these arteries are needed to keep a person alive. These areas control breathing, heart rate, swallowing, vision, movement, and posture or balance. All of the nervous system signals that connect the brain to the rest of the body pass through the back of the brain.
Many different conditions may reduce or stop blood flow in the back part of the brain. The most common are smoking, high blood pressure, diabetes, and a high cholesterol level. These are similar to the risk factors for any stroke.
