PURPOSE: Diagnostic cerebral venograms are the gold standard for evaluating cerebral venous sinus stenosis (CVSS). Venous sinus stenting (VSS) and less commonly venous sinus angioplasty are emerging endovascular treatments in pediatric patients. This study examines the baseline intracranial venous pressures and postoperative endovascular outcomes in pediatric patients with CVSS.
METHODS: A retrospective chart review was performed on patients ≤ 18 years old with CVSS between October 2021 and August 2024.
RESULTS: A total of fifteen patients with CVSS underwent 20 endovascular procedures. The average age was 13.0 years of age (IQR 6-15 years of age) and 53.3% female. Eight patients (53%) were diagnosed with IIH by the revised Friedman criteria. Papilledema was present in 73.3% of patients with an average lumbar puncture or ventriculostomy opening pressure of 409 mmH2O. The average superior sagittal sinus (SSS) pressure was 24.3 mmHg (range 13-50 mmHg). The average trans-stenotic gradient was 8.5 mmHg (IQR 4.0-13.3; n = 14). Five patients underwent dural venous sinus stenting (mean pre-stent TSG of 17.0) with a significant reduction in the trans-stenotic gradient of 13.5 mmHg (p = 0.04; 79.4% relative reduction). One of these VSS patients developed stent adjacent stenosis (SAS) at follow-up requiring further venous sinus stenting. There was one peri-operative complication (5%) involving a retroperitoneal hematoma.
CONCLUSION: Initial dural venous sinus stenting significantly reduced the trans-stenotic gradient in all pediatric CVSS patients. Of the patients who underwent venous sinus angioplasty, 100% required further surgical intervention for management of their ICPs. There was one perioperative complication (5%) associated with CVSS endovascular interventions.
