Targeting the Bottleneck: Transverse Sinus Stenting in Idiopathic Intracranial Hypertension – A Case Report
Sneha Sri Murali*, Dinesh Sharma and Bhawana Sonawane
ABSTRACT
Background: Idiopathic intracranial hypertension (IIH) is characterized by raised intracranial pressure without an identifiable intracranial mass, hydrocephalus, or infection. Increasing evidence supports the role of transverse sinus stenosis in the pathophysiology of IIH. Venous sinus stenting has emerged as an effective treatment in selected patient’s refractory to medical therapy.
Methods: This manuscript includes a case of transverse sinus stenting performed for refractory IIH along with a descriptive analysis of ten patients diagnosed with IIH based on clinical and imaging criteria.
Results: stented patients demonstrated significant trans-stenotic pressure gradients and showed immediate clinical and radiological improvement following stenting. Among the ten IIH patients, MR imaging commonly demonstrated empty sella, optic nerve sheath distension, and transverse sinus stenosis.
Conclusion: Transverse sinus stenting is a safe and effective minimally invasive treatment in carefully selected IIH patients. MRI with MR venography plays a pivotal role in diagnosis, patient selection, and follow-up.
