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
introductionDigital subtraction angiography (DSA) remains the gold standard for diagnosing and managing cerebrovascular diseases, despite the increasing use of noninvasive imaging modalities. Traditionally performed in catheterization labs by interventional radiologists, the integration of DSA into neurosurgery operating theaters (OT) using 3D C-arm technology offers neurosurgeons greater control over diagnosis and treatment planning, reducing dependency on external specialists.
objectiveThis study aims to describe the initiation and implementation of a DSA program in a neurosurgery OT using 3D C-arm technology, detailing the technique, procedural nuances, and associated benefits. By sharing our institutional experience, we seek to provide a valuable resource for neurosurgeons interested in establishing similar programs.
methodsBetween October 2023 and January 2025, 100 diagnostic DSA procedures were performed in our neurosurgery OT utilizing a multi-axis 3D C-arm (Ziehm Vision RFD 3D, Ziehm Imaging, Germany). Patient selection criteria, procedural protocol, radiation safety measures, and complication management strategies were meticulously developed. Arterial access was obtained via the right femoral artery, and angiographic views were optimized to ensure comprehensive cerebrovascular evaluation. Post-procedural care included hemostasis, neurological monitoring, and complication prevention.
resultsAmong the 100 DSA procedures performed, the most common indication was spontaneous subarachnoid hemorrhage (SAH) in 88 cases (88%). Two patients underwent intra-arterial nimodipine injection for vasospasm management post-aneurysm clipping. No major complications, including stroke or mortality, were encountered. Challenges such as radiation safety, staff training, and equipment acquisition were successfully addressed, leading to improved efficiency and procedural safety over time.
conclusionsThe successful implementation of a DSA program in the neurosurgery OT using 3D C-arm technology underscores its feasibility and benefits. Neurosurgeons, with their deep understanding of cerebrovascular anatomy and pathology, are well-positioned to perform DSA, manage complications, and advance endovascular capabilities. This initiative highlights the potential for hybrid neurosurgical practice, bridging the gap between open microsurgery and endovascular interventions, ultimately improving patient outcomes and advancing neurovascular care.
