Venous Sinus Stenting Using a Ledge-Reducing Catheter, 0.088-in. Catheter-Extender With an External Single Point of...

Area of Science:

• Neurosurgery
• Interventional Radiology
• Vascular Medicine

Background:

• Venous sinus stenting (VSS) is an emerging treatment for idiopathic intracranial hypertension (IIH) and pulsatile tinnitus.
• The Monopoint System (MS) is a novel telescoping catheter designed for VSS procedures.
• This study evaluates the MS technique and clinical outcomes in a multicenter setting.

Purpose of the Study:

• To describe the technique for VSS using the Monopoint System.
• To assess the safety and efficacy of the MS in a multicenter clinical experience.
• To evaluate operator satisfaction with the MS for VSS.

Main Methods:

• Retrospective review of 71 patients undergoing VSS with MS across 13 sites (2022-2023).
• Detailed description of the MS catheter manipulation for stent delivery.
• Operator survey on MS performance compared to traditional methods.

Main Results:

• Successful stent deployment in all patients (n=71).
• Significant reduction in venous sinus stenosis (80% to 0%, P<0.001).
• High rates of symptom improvement: headache (81%), pulsatile tinnitus (95%), papilledema (91%).
• No Monopoint-related complications reported.
• Operators rated MS superior in 99% of cases for ease of use and performance.

Conclusions:

• The Monopoint System is a safe and effective catheter platform for venous sinus stenting.
• MS facilitates successful VSS procedures with high clinical success and patient satisfaction.
• The system offers advantages in crossing stenotic lesions and stent delivery.
