Follow-up imaging characteristics of a Novel Braided Stent (BosSTENT™) in treating transverse sinus stenosis related to venous congestion and/or pulsatile tinnitus
Bibliographic record
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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
