Abstract

Objective: To evaluate the efficacy and safety of the novel Femoral-Long Sheath-Reshape-Anchoring-Stenting (FLRAS) technique (developed by Dr. Hongbo Zheng) for venous sinus stenting in patients with idiopathic intracranial hypertension.

Design: Retrospective, single center study.

Materials and methods: 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 (described in this mansucript) from May 2015 to May 2018.

Results: A total of 20 patients (mean age, 36.7 [range, 17-50] years; 15 women) were enrolled in the study. In FLRAS group (n=12) vs. traditional stenting group (n=8): mean procedure duration was significantly shorter (48.3 min vs. 92.5 min, P <0.001), and procedure success rate was numerically higher (100% vs. 87.5%, P>0.05), with no vs. 2 complications, respectively.

Conclusions: Use of FLRAS technique for venous sinus stenting in patients with idiopathic intracranial hypertension appeared to yield favorable outcomes relative to use of the traditional stenting technique. A large, multicenter, randomized study is warranted to confirm these findings.
