Cerebral venous pressures, sinus trans-stenosis gradients, and intracranial pressures are dramatically augmented by head position.

Head position significantly affects cerebral venous pressures, trans-stenosis gradients, and intracranial pressures in patients with CVD or intracranial hypertension. These findings highlight the need for dynamic venography in the diagnostic evaluation of these conditions to better understand their pathophysiology and improve treatment strategies.
