Brain Imaging in Cerebral Venous Outflow Disturbance

Cerebral venous outflow disturbance can lead to cerebral hemodynamic disturbances, altered cerebrospinal fluid dynamics, cerebral venous blood stasis, increased cerebral venous pressure and decreased cerebral perfusion, cerebral white matter sparing-like changes, and widening of retinal vessel diameter. These changes are associated with numerous neurological signs and symptoms. A number of central nervous system disorders such as transient global amnesia, transient monocular blindness, primary labor headaches, and even Parkinson's have been reported to be closely associated with internal jugular vein stenosis. Other common clinical manifestations include sleep disturbances, tinnitus, tinnitus, headache, visual impairment, optic papilledema, hearing loss, cognitive decline and neck discomfort and even autonomic dysfunction. The main objective of this study is to investigate the structural and functional network changes in patients with cerebral venous outflow disturbance using different brain imaging techniques, to clarify the correlation between symptoms of cerebral venous outflow disturbance and brain structure and function; to identify areas with corresponding structural and functional changes in patients with cerebral venous outflow disturbance and or comorbid symptoms, and to provide specific imaging assessment indicators and new diagnostic and treatment tools for patients with cerebral venous outflow disturbance and comorbid symptoms.
