Comparison of venous sinus manometry gradients obtained while awake and under general anesthesia before venous sinus stenting

Introduction Venous sinus stenting is a popular treatment strategy for patients with high venous sinus pressure gradients across a site of outflow obstruction. Little is known about the effect of anesthesia on venous sinus pressure measurements. Objective To compare venous manometry performed in patients under general anesthesia and while awake. Methods A prospective database was accessed to retrospectively identify patients who had undergone...
