Сerebral venous dyscirculation in patients with cervicogenic headache

Abstract

Clinical and Doppler examination of 146 patients was carried out young age (18–44 years, including men – 75, women – 71) with cervicogenic headache. All patients were divided into two clinical groups: group 1 – cervicocranialgia – 82 patients; group 2 – posterior cervical sympathetic Barre-Lieou syndrome – 64 patients. By help triplex transcranial scanning has been studied high- speed blood flow indicators in the supraocular and vertebral veins, basal veins of Rosenthal, sinus rectus, as well as reactivity coefficients in the vertebral veins, basal veins of Rosenthal and direct sinus at applications and orthostatic and antiorthostatic functional loads. All patients were determined Doppler and signs of cerebral venous dyscirculation, mainly in the vertebral veins. Signs of venous dyscirculation were manifested in the vertebral veins and sinus rectus in patients with cervicocranialgia, as well as in vertebral veins in patients with Barre-Lieou syndrome. Leading pattern there was a violation of autoregulation of cerebral venous blood flow hyporeactivity to orthostatic and antiorthostatic loading in the vertebral veins, more pronounced in patients with cervicocranialgia. Easy hyperreactivity to antiorthostatic load on the basal veins of Rosenthal and sinus rectus in patients of both groups indicates a violation of the neurogenic mechanism in the regulation of venous blood flow
