Internal jugular vein stenosis induced intracranial hypertension can be resolved by stenting
Abstract BackgroundIdiopathic intracranial hypertension (IIH) is characterized by abnormally elevated intracranial pressure (ICP) without identifiable etiology. Recently, however, a subset of patients with presumed IIH have been found with isolated internal jugular vein (IJV) stenosis in the absence of intracranial abnormalities. MethodsFifteen consecutive patients were screened from 46 patients suspected as IIH and were finally confirmed as isolated IJV stenosis. The stenotic IJV was corrected with stenting when a trans‐stenotic mean pressure gradient (∆MPG) was equal or higher than 5.44 cmH2O. Dynamic MRV/CTV/DSA of IJV, ∆MPG, ICP, Headache Impact Test‐6 (HIT‐6) and Frisén papilledema grade (FPG) score before and after stenting were compared. ResultsAll the stenotic IJVs were corrected by stenting. ∆MPG decreased and the abnormal collateral veins disappeared or shrank immediately. Headache, tinnitus, papilledema and ICP were significantly ameliorated at 14 ± 3 days of follow‐up (all p
We report two cases which presented with acute onset spontaneous CSF rhinorrhoea without any other symptom. In addition, we discuss in detail imaging features of IIH with review of its literature.
Conclusion: Risk factors associated with sinus thrombosis must be always investigated; endovascular treatment is safe and reasonable in a clinical deterioration scenario.Pediatr Neurosurg
Conclusion: Stent-adjacent stenosis is an important complication following venous stenting in patients with DVSS and IIH. Further studies are needed to identify determinants of stent-adjacent stenosis and stent nonsurvival.Intervent Neurol 2018;7:490 –500
CONCLUSIONS Transverse sinus stenting is a rapidly developing technique that has shown good effectiveness and safety in the literature. Authors of the present study found that stenting a flow-obstructed transverse sinus in patients with IIH was a safe and effective way to treat the condition. PMID: 29961386 [PubMed - in process]
Conclusions The study establishes that there is a relationship between presence of AG and IIH. Arachnoid granulation seems to act in a compensatory mechanism in patients with IIH.
