TRANSCRANIAL DOPPLER IN PATIENTS WITH TENSION HEADACHE AND CERVICOGENIC HEADACHE

Kharkiv Medical Academy of Postgraduate Education, Ukraine

Tension headache (TH) and cervicogenic headache (CH) are the best−known and most common neurological diseases occurring in adults. To study was performed to assess cerebral hemodynamics using transcranial duplex scanning in patients with different types of TH and CH. The parameters of the linear blood flow velocity (BFV) in the cerebral arteries and maximal blood flow velocity (Vmax) in vertebral veins (VV), Rosenthal basal veins (RBV) and straight sinus (SS) were investigated using transcranial Doppler sonography at rest and under functional loads. Hemodynamic disturbances in the studied persons with TH often manifested in the form of strengthened BFV in the middle cerebral arteries and asymmetry of the BFV. Patients with CH manifested vasospasm in both vertebral arteries (VA), vasospasm in one VA and/or basilar arteries (BA), blood flow asymmetry through VA. The majority of patients with TH had increased Vmax in the SS and BVR, and the vast number of patients with CH had increased Vmax in the VV and SS, and hyperreactivity in VV and SS compared to the control set. Cerebral hemodynamics in patients with tension headache is characterized by angiodystonic phenomena, venous disgemia in the form of increased outflow from SS and BVR and hyperreactivity during ortho− and antiorthostatic loads in SS and BVR. In patients with cervicogenic headache vasospastic reactions in VA and BA, venous discirculation in VV and TS dominate.
