Increased blood flow in the vertebrobasilar artery is associated with dizziness, headache, chest tightness, chest pain, tinnitus, and memory loss. Clinically, increased blood flow in the vertebral basilar artery, which is mainly found when transcranial Doppler ultrasound is performed, is usually caused by atherosclerosis as well as spasm of the vertebral basilar artery. Secondly, spasm of the vertebral arteries may also cause increased blood flow. Atherosclerosis usually involves different organs, resulting in corresponding symptoms of ischemia and hypoxia, such as dizziness, headache, chest tightness, chest pain, and persistent high blood pressure when the heart and brain are involved. Spasm of vertebral basilar artery will be compressed by cervical bone spurs, resulting in narrowing of blood vessels, which will reduce blood and oxygen supply to the brain, resulting in neck pain, memory loss, tinnitus and other discomforts. It is recommended to go to the hospital in time for standardized treatment under the guidance of the doctor after the occurrence of the above mentioned symptoms.
