Next, a 0.027 inch microcatheter will be navigated using fluoroscopic guidance into the superior sagittal sinus and a venogram will then performed by injecting a small dose of contrast. Next, the venous sinus pressure waveforms will be recorded as the catheter is withdrawn into the jugular bulb and then in the superior vena cava to obtain a central venous pressure. Once completed, the catheters will be removed and the sheaths will be removed. Manual pressure will be held at the venous access site for a few minutes. The arterial sheath will be closed based upon standard arteriogram protocol.",[9],null,[21],{"name":22,"affiliation":5,"role":23},"Kyle Fargen, MD","PRINCIPAL_INVESTIGATOR",[25,30],{"name":26,"role":27,"phone":28,"phoneExt":19,"email":29},"Kimberly Hawley","CONTACT","336-716-4031","kimberly.hawley@advocatehealth.org",{"name":22,"role":27,"phone":19,"phoneExt":19,"email":31},"kyle.fargen@advocatehealth.org",[33],{"facility":34,"status":35,"city":36,"state":37,"zip":38,"country":39,"countryCode":40,"cosmosGeoPoint":41,"geoPoint":46,"contacts":19},"Wake Forest Univesity Health Sciences","RECRUITING","Winston-Salem","North Carolina","27157","United States","US",{"type":42,"coordinates":43},"Point",[44,45],-80.24422,36.09986,{"lat":45,"lon":44},{"type":48,"investigatorFullName":19,"investigatorTitle":19,"investigatorAffiliation":19,"oldNameTitle":19,"oldOrganization":19},"SPONSOR","100358584","prospective-measurement-of-normal-venous-sinus-pressures-100358584",false,"NCT03948971","Prospective Measurement of Normal Venous Sinus Pressures","Venous Sinus Pressures in Normal Individuals","Inclusion Criteria:\n\n* Candidates for elective cerebral arteriography\n\nExclusion Criteria:\n\n* All patients with active, or a history of, intracranial venous pathology (arteriovenous malformation, arteriovenous fistulae, idiopathic intracranial hypertension, venous sinus thrombosis).\n* Patients with severe daily headaches or symptoms of idiopathic intracranial hypertension will also be excluded.\n* Body mass index \\> 35.\n* Known diagnosis of heart failure or pulmonary hypertension.\n* Pregnant women will be excluded due to the radiation risk associated with Angiogram and Venogram.","ALL","18 Years","60 Years",{"count":60,"type":61},10,"ESTIMATED","INTERVENTIONAL",[64],"NA","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.",[67],"Intracranial Venous Pressures",[69],"cerebral arteriography","2026-05-22",{"date":72,"type":73},"2026-05-26","ACTUAL",{"date":75,"type":73},"2020-01-13",{"date":77,"type":61},"2027-05",{"name":5,"class":6},1]
