Use of the LEONIS Mova Steerable Catheter in the Treatment of Cavernous Sinus Dural Arteriovenous Fistula with Occluded Inferior Petrosal Sinus.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: LEONIS Mova high-flow type (SB-KAWASUMI LABORATORIES, Kanagawa, Japan) is a steerable microcatheter that enables angle adjustment of the catheter tip using a hand-operated dial, and available as a coaxial microcatheter system with a 1.6-F microcatheter. It was used to navigate an occluded inferior petrosal sinus (IPS) in a patient with cavernous sinus (CS) dural arteriovenous fistula (AVF). Case Presentation: A man in his 50s presenting with right eye congestion was diagnosed with dural AVF of the CS with bilateral occluded IPSs. The shunted pouch was located in the medial-lateral part of the right CS, with drainage into the superior ophthalmic vein. Transvenous embolization (TVE) from the femoral vein via the occluded IPS was performed. A 6-F guiding catheter was navigated to the right internal jugular vein, and LEONIS Mova high-flow type combined with a 1.6-F Carnelian MARVELS S microcatheter (Tokai Medical Products, Aichi, Japan) was navigated to the occluded IPS. The LEONIS Mova successfully engaged the IPS, and its tip was fixed by adjusting the curve. The microcatheter advanced smoothly into the right CS. After releasing the fixation of the LEONIS Mova, the microcatheter was advanced further into the CS, where the LEONIS Mova was once again fixed. The microcatheter was easily navigated to the shunted pouch, and targeted coil embolization of the shunted pouch, achieving complete occlusion of the dural AVF. Conclusion: The LEONIS Mova steerable catheter offers flexible angle adjustment and strong support for catheter navigation within an occluded IPS during TVE for CS-dural AVF.
