Abstract
BackgroundVenous sinus stenosis (VSS) is a type of cerebral venous vascular disease. Cerebral autoregulation is an indicator of cerebral arterial function. The cerebral circulatory system is composed of the venous system and arterial system. Impaired venous function may affect arterial function. Thus, cerebral venous stenosis may influence cerebral autoregulation.Case presentationIn this case, a 50-year-old woman with transient blindness and headache was admitted to the hospital. The patient was diagnosed with VSS. A stent was placed at the stenosis. The stent released the intravenous pressure and remitted the patient’s symptoms. Measurements of dynamic cerebral autoregulation (dCA) were performed at 3 time points: before stenting, after stenting, and 3 months later. The dCA gradually improved after stenting.ConclusionVSS may have an influence on cerebral autoregulation, and effective treatment improves cerebral autoregulation in patients with VSS.

Summary
Venous sinus stenosis (VSS) is a type of cerebral venous vascular disease. Cerebral autoregulation is an indicator of cerebral arterial function. The cerebral circulatory system is composed of the venous system and arterial system. Cerebral venous stenosis may influence cerebral autoregulation. CA is an indicator of cerebral arterial function. Research has indicated that impaired CA is associated with cerebral small vessel disease, cerebral hemorrhage, and unilateral middle cerebral artery stenosis [1,2,3]. These diseases are directly related to the cerebral artery. Venous sinus stenosis (VSS) is a kind of cerebral venous system disease that obstructs venous blood outflow. Some studies have shown that it may cause increased intravenous pressure, decreased
