Case Report: A novel strategy for superior petrosal vein management in cerebellopontine angle surgery.
Article in Frontiers in oncology, 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
The superior petrosal vein (SPV) is a vital venous drainage system in the posterior fossa. It is often sacrificed during cerebellopontine angle (CPA) surgery to enhance surgical exposure, leading to postoperative complications. This study introduces the "Venous Flow Redistribution" (VFR) technique, a novel approach that preserves the SPV's main venous trunk while severing its distal connections, thus enabling optimal tumor exposure and minimizing venous injury. We present a case of right-sided CPA meningioma treated with suboccipital retrosigmoid craniotomy and the VFR technique. Postoperatively, the patient had an uneventful recovery with improvement in headache and hearing loss, without any complications. The VFR technique leverages multiple venous collateral pathways, redistributing venous flow and maintaining drainage, thereby enhancing surgical flexibility while reducing the risk of complications. This method might be a promising strategy for SPV preservation during complex CPA surgeries.
