Summary
The purpose of this research is to document normal intracranial venous sinus pressures. Participants who need to have a cerebral angiogram to evaluate a medical problem not related to Idiopathic Intracranial Hypertension (IIH) will be invited to participate. Participation in this research will not require any extra visits. The intervention will take place in the interventional radiology suite when the subject has an angiogram. IIH is a condition that causes increased pressure in the brain in the absence of a tumor or other diseases that may be causing symptoms. Symptoms include headaches and visual disturbances not explained by other things. In IIH there is a narrowing in the sinuses of the brain that causes the increased pressure.
Description
Patients will be prospectively enrolled into the study. All adult patients, aged of 18-60, determined to be candidates for elective cerebral arteriography will be screened for inclusion in this study. Patients consenting to participate and enrolled in the study will first undergo their standard cerebral angiogram procedure, as clinically indicated. Once the procedure is completed, enrolled subjects will then undergo the study intervention.
- Insertion of an additional catheter in the femoral vein.
- Navigation of the catheter into the internal jugular bulb and then catheter navigation into the superior sagittal sinus will result in additional fluoroscopic time (requires ~60 seconds of additional fluoroscopy time; carries a minimum risk of vessel perforation or other untoward event [incidence of complication associated with this procedure in the PI patient series is 0%]). There is additionally some ear pain that can happen with this Venogram.
- 5-10 minutes of additional procedure time. Much of this time period is merely a waiting period while the pressures stabilize and are recorded.
- An additional venogram injection through the catheter which exposes subjects to an additional 1-2 ml of contrast dye and 3-4 seconds of additional fluoroscopy time and its associated radiation dose.
