Measuring normal brain vein pressure during angiograms
Part of Brain & nervous system clinical trials.
This study measures pressure in the brain’s draining veins during a planned (elective) brain angiogram. It may help doctors better understand “normal” vein pressure, especially for people being evaluated for other conditions.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You need to be scheduled for an elective brain angiogram (cerebral arteriography).
- You do not have a known past or current problem with brain venous drainage (like vein blood clots, abnormal blood vessel connections, or idiopathic intracranial hypertension).
- You should not have severe everyday headaches or symptoms that suggest idiopathic intracranial hypertension.
- Your body mass index (BMI) must be 35 or lower.
- You should not have heart failure or pulmonary hypertension.
- You must not be pregnant during the planned angiogram.

Other trials that look related to this one.
This study looks at how placing a catheter (thin tube) in a neck vein during surgery affects pressure inside the brain. Researchers will use ultrasound to measure this pressure and help doctors understand if this common procedure impacts brain blood flow.
This study looks at how blood vessel function relates to brain blood flow in patients in intensive care with brain injuries or conditions. It aims to find better ways to monitor patients using non-invasive tools.
This study uses eye scans to see if changes in the retina can help doctors measure pressure inside the skull. It may help find a safer way to check for high pressure in the brain without needing a needle in the back.
This study tests a new way to estimate pressure inside the skull without extra needles or surgery. It uses a soft mask and ultrasound to measure pressure at a vein near the eye, aiming to find a safer alternative for people who already have a standard brain-pressure monitor in place.
This study tests a new way to measure pressure inside the skull by using a small vein near your eye. It is for people who are already having a routine test to check fluid pressure around the brain.
This study uses MRI scans to look at how fluid drainage and white matter are affected in people with narrowed or blocked veins in the brain. It aims to understand if these vein problems harm the brain's natural cleaning system.
