Cerebral Venous Sinus Stenosis may Cause Intracranial Arterial Hypoperfusion

Cerebral venous sinus stenosis (CVSS) is always thought of being associated with raised intracranial pressure (ICP) . Persistent high ICP conduces refractory headache, papilledema and even irreversible visual disturbance [1, 2]. In addition, some symptoms not correlated with high ICP, such as tinnitus, sleep disorder and head noise, are likely caused by increased transstenosis pressure gradient (>8 mm Hg) . Revascularization of venous sinuses and outflow correction can decrease the abnormally elevated ICP and the pressure gradient, both of which are further confirmed as the causative role in the symptoms of CVSS [4, 5]. Although the venographic characteristics of CVSS have been fully reported, the cerebral perfusion status that can also contribute to the symptoms is still unknown. This study reports a female with CVSS-induced cerebral arterial perfusion disorder that returned to normal after stenting across the sinus stenoses, in an attempt to explore the impact of...
