Abstract Objective To analyze and explore the diagnostic value of transcranial Doppler ultrasonography on vascular headache,and to observe the changes of cerebral blood flow by means of transcranial Doppler examination for patients with vascular headache. Methods 162 patients with vascular headache admitted to were selected as the observation group,and another 60 healthy people during the same period were selected as the control group.A 2MHz probe was used to probe the vascular conditions and blood flow changes of anterior cerebral artery,middle cerebral artery,posterior cerebral artery,basilar artery and vertebral artery of patients. Results The average blood flow velocities of anterior cerebral artery,middle cerebral artery,posterior cerebral artery,basilar artery and vertebral artery of the observation group were significantly higher than those of the control group（P<0.001）.The abnormal rate of vascular vertebral artery in patients with vascular headache was the highest,reaching 97.53%.The abnormal rate of basilar artery was the lowest,accounting for 51.23%.The type of vascular abnormality was mainly the acceleration of blood flow,and the occurrence of vascular murmur was the least. Conclusion The average blood flow velocities of cerebral blood vessels of patients with vascular headache are significantly higher than those of healthy people.Transcranial Doppler ultrasonography can accurately detect the changes of cerebral blood flow of patients with vascular headache,and has a higher diagnostic value in the diagnosis of vascular headache.
