On Feb 22nd, Dr. Omar Choudhri presented Novel Advanced Imaging & Treatment Paradigms for Patients with IdiopathicThe term idiopathic is used when there is no detectable reason for something. Intracranial Hypertension and Pulsatile TinnitusA whooshing or throbbing noise heard in one or both ears that can range from annoying to debilitating. Highly associated with venous sinus stenosis.. Dr. Omar Choudhri is a neurosurgeonMedical doctor who diagnoses and treats surgical issues related to the brain, spine, and nervous system. and neurointerventionalist and is an Assistant Professor of Neurosurgery and Radiology at the University of Pennsylvania. The moderator for this lecture is Dr. Pierre Gobin. He is a neurointerventionalist at Weill Cornell Medicine in New York with more than 30 years of experience in treating cerebrovascular conditions.

- Although the exact mechanism of IIH is unknown, there are multiple factors that contribute to its pathophysiology such as centripetal (central) adiposity, immune, inflammatory, glymphatic and lymphatic dysfunction.
- There is a correlation between patients with IIH and an increased central adiposity.
- IIH occurs when there is an imbalance of cerebrospinal fluidFluid that is made by specialized cells in the ventricles of the brain. production and absorption
- Over 90% of patients with transverse sinus stenosisNarrowing of the transverse sinus of the brain. It is a likely source of intracranial hypertension seen in patients with IIH. is seen with MR imaging
- Venous sinus stenosis is seen on imaging in almost 90% of IIH patients
- Venous manometryA minimally invasive involving the introduction of instruments or other objects into the body diagnostic procedure performed by a neurosurgeon or interventional neuroradiologist where a catheter… is essential to corroborate noninvasive imaging findings. At times, even if there is narrowing of a vessel seen on imaging, it does not always translate to impaired flow. Venous manometry can provide helpful information such as if there is a pressure gradient.
- Dr. Choudhri explained novel advanced imaging to help aid in the diagnosis and treatment of IIH such as: retrograde balloon assisted phlebography, fusion 3D imaging, temporal bone high resolution DYNA CT and access through the right upper extremity.
We thank Dr. Choudhri for his expertise and devotion to IIH. If you would like to get in touch with Dr. Choudhri or see him as a patient click here.
Our next live webinar will be held in April. We will be hosting a chat session and focus on Navigating Through the Healthcare System with IIH. We will keep you posted on the date and time. If you would like to stay informed, click here.
