Pathophysiology
Pathophysiology of <strong>RCVS</strong> - ‘migrainous vasospasm’ - ‘mechanical’: catheter-induced vasospasm - ‘angiographic dye’ - bradykinin - sympathomimetic (ergot, amphetamine, cocaine) - endothelin-1, nitric oxide, substance P, CGRP - female reproductive hormones - serotonin - calcium
