Advanced Neuroimaging in Idiopathic Intracranial Hypertension
NCT06950099 · View on ClinicalTrials.gov ↗
Study Summary
Idiopathic intracranial hypertension (IIH) is characterized by elevated intracranial pressure leading to symptoms like papilledema, headache, and cognitive dysfunction. While the etiology is complex, abnormal cerebrospinal fluid dynamics due to venous outflow restriction from transverse sinus stenosis (TSS) is common. TSS may disrupt the glymphatic system, a brain-wide network facilitating cerebrospinal fluid and interstitial fluid exchange, by impairing CSF absorption, altering perivascular space dynamics, and disrupting pressure gradients crucial for waste clearance. Venous sinus stenting (VSS) can improve symptoms in many patients by alleviating venous congestion, but its effects on glymphatic function are unclear. This prospective study aims to evaluate novel quantitative brain imaging metrics as surrogate markers to better understand IIH pathophysiology before and after VSS in patients with refractory IIH and TSS. The investigators will use advanced MRI techniques, including MR elastography (MRE) to assess brain stiffness, diffusion tensor imaging (DTI) to evaluate water diffusion, arterial spin labeling (ASL) imaging to measure blood-brain barrier (BBB) permeability, and functional MRI to analyze pain networks. The investigators hypothesize that 1) these noninvasive imaging metrics will correlate with the degree of venous congestion and changes after venous sinus stenting (VSS) and 2) the imaging findings will correlate with clinical treatment outcomes. By correlating imaging markers with venous pressures and symptom changes, the investigators aim to gain insights into IIH mechanisms, expand diagnostic tools, and potentially guide clinical decision-making and treatment response monitoring. The overarching goal is to better understand IIH's underlying pathophysiology, which could lead to improved diagnostic criteria, more targeted treatments, and better prediction of treatment outcomes for patients with this challenging condition.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT06950099
The ClinicalTrials.gov registry entry for NCT06950099 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 30 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Thomas Jefferson University, which has 324 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Idiopathic Intracranial Hypertension (IIH) appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT06950099 reports 1 study location spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
