The Effects of MAP and EtCO2 on Venous Sinus Pressures

Prospective Measurement of Blood Pressure and End Tidal Carbon Dioxide Content Effects on Venous Sinus Caliber and Pressures in Patients With Idiopathic Intracranial Hypertension Undergoing Stenting

The purpose of this study is to further elaborate the role of both arterial blood pressure and end-tidal carbon dioxide concentration on measured venous pressures.

To prospectively evaluate the effect of changes in end-tidal carbon dioxide and arterial blood pressure on venous sinus pressure measurements in patients undergoing venous sinus stenting under general anesthesia. Venous sinus pressure measurements will increase with increases in both arterial blood pressure and end-tidal carbon dioxide concentrations.

Inclusion Criteria:

• Adults determined to be candidates for venous sinus stenting
