Follow-up imaging characteristics of a Novel Braided Stent (BosSTENT™) in treating transverse sinus stenosis related to venous congestion and/or pulsatile tinnitus.
Article in Interventional neuroradiology : journal of peritherapeutic neuroradiology, surgical procedures and related neurosciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It carries an expression of concern. Cited by 1 paper.
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
BackgroundTransverse sinus stenosis (TSS) is increasingly recognized as a key contributor to pulsatile tinnitus (PT) and cerebral venous congestion (CVC), including idiopathic intracranial hypertension (IIH). While venous stenting has shown promising clinical outcomes, long-term imaging data on dedicated braided stents remain limited.ObjectiveTo report the clinical and imaging outcomes of the BosSTENT™, a novel self-expanding braided stent, in patients with symptomatic TSS.MethodsThis retrospective study included 27 consecutive patients treated at a single institution between December 2022 and December 2024. All patients presented with PT, with or without chronic headaches or signs of intracranial hypertension. Patients underwent BosSTENT™ deployment and were followed clinically and radiologically for up to 2 years. Outcomes included symptom resolution, procedural safety, and long-term stent integrity based on structured imaging protocols.ResultsOf the 27 patients (96.3% female, mean age 41.4 years), 26 have long-term follow-up, 96.2% achieved overall improvement of PT and 84.6% experienced complete or significant improvement in headaches. One patient experienced a fatal subdural hematoma unrelated to device performance, and two patients had femoral access site complications. Imaging follow up confirmed persistent stent patency and structural integrity in all cases, with no instances of thrombus, in-stent stenosis, migration, fracture, or adjacent stenosis.ConclusionThe BosSTENT™ demonstrates favorable long-term safety and performance in the treatment of symptomatic transverse sinus stenosis. These findings support its role as a dedicated device for venous sinus stenting, particularly in patients with pulsatile tinnitus and intracranial hypertension.
