Femoral-Long Sheath-Reshape-Anchoring-Stenting (FLRAS) Technique in Venous Sinus Stenting for Idiopathic Intracranial Hypertension

Objective To evaluate efficacy and safety of the novel femoral-long sheath-reshape-anchoring-stenting (FLRAS) technique for venous sinus stenting in patients with idiopathic intracranial hypertension. Methods In a retrospective, single-center study, we comparatively analyzed clinical and imaging data from consecutive patients with idiopathic intracranial hypertension who underwent venous sinus stenting using either traditional technique from June 2013 to May 2015 or FLRAS technique from May 2015 to May 2018. Results The study enrolled 20 patients (mean age 36.7 years; range, 17–50 years; 15 women). In the FLRAS group ( n  = 12) versus traditional stenting group ( n  = 8), mean procedure duration was significantly shorter (48.3 minutes vs. 92.5 minutes, P P > 0.05), with no complications versus 2 complications. Conclusions Use of FLRAS technique for venous sinus stenting in patients with idiopathic intracranial hypertension appeared to yield favorable outcomes relative to use of traditional stenting technique. A large, multicenter, randomized study is warranted to confirm these findings.
