Abstract No. 570 Case-based analysis of cerebral venous pathology: a proposed pathophysiological mechanism.

Parameters recorded included patient demographics, location of stenosis, pre- and posttreatment manometric venous sinus and internal jugular pressure measurements, and symptoms before and after treatment. Posttreatment mean gradients were 2 mm Hg for venous sinus stenosis and 1.5 mm Hg for jugular stenosis (no treatment yet for the C1-level patient). Intracranial hypertension caused by venous stenosis is a complex pathophysiological phenomenon with symptoms that correlate with observed manometric findings. [Extracted from the article]
