Venous sinus stenting for pulsatile tinnitus secondary to venous sinus stenosis: a dual-center retrospective cohort study.
Article in Neurosurgical review, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pulsatile tinnitus (PT) can emerge due to stenosis in the venous sinus, which leads to turbulent venous flows and increased pressures within the veins. Stenting of the venous sinus (VSS) is a potential intervention to relieve PT and is considered minimally invasive, as it restores proper venous flow. To evaluate the clinical, hemodynamic, and radiological outcomes of venous sinus stenting (VSS) in a real-world cohort of patients with pulsatile tinnitus (PT) and venous sinus stenosis, and to describe the symptom-imaging-manometry framework used for procedural selection in routine practice. From January 2018 to December 2024, we conducted a dual-center, retrospective cohort study of 30 consecutive adults with PT who underwent transverse sinus stenting. Secondary outcomes included changes in trans-stenotic venous pressure gradient, early 1-month change in LP opening pressure, radiologic resolution, papilledema improvement, procedure-related complications, and recurrence. Thirty patients were included (28 females; mean age 39.0 ± 13.1 years). PT was right-sided in 50.0%, left-sided in 16.7%, and bilateral in 33.3%. Mean pre-stent trans-stenotic pressure gradient was 7.0 ± 1.4 mmHg and decreased significantly after stenting (P < 0.001). LP opening pressure decreased from 39.93 ± 10.99 before stenting to 18.23 ± 3.87 cm H₂O at 1 month after stenting (P < 0.001). Immediate complete symptom resolution occurred in 27 patients (90%); the remaining 3 patients (10%) achieved complete resolution by 12 months of follow-up. Follow-up MRV demonstrated resolution of the treated venous sinus stenosis, with restored sinus caliber/patency in all patients. Minor complications occurred in 3 patients (10%) (ecchymosis 6.7%, epistaxis 3.3%), with no major adverse events or recurrence. VSS was associated with a significant reduction in venous pressure gradient and LP opening pressure, along with high durable PT resolution rates and a low rate of minor complications in this cohort.
