Intracranial Venous Sinus Stenting
Intracranial venous sinus abnormalities can obstruct the outflow of blood from the head. In some patients who have chronically elevated intracranial pressures, venous outflow obstruction may be a related finding. For evaluation, patients often undergo diagnostic brain imaging such as MRI or MR angiography, detailed eye examination, and an endovascular procedure to perform manometry testing to evaluate intracranial pressures in several locations. Selected patients may benefit from placement of a stent within a dural sinus of the head to improve venous outflow. The stent is delivered using standard neuroendovascular techniques and on occasion a balloon is also inflated within the stent to ensure optimal placement.
