Ruptured aneurysm of the middle cerebral artery with cerebral herniation treated with Woven EndoBridge via distal radial artery access: a case report.
Article in Journal of medical case reports, 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
backgroundRuptured intracranial aneurysm (RIA) is the leading cause of spontaneous subarachnoid hemorrhage (SAH), with a high disability and mortality rate. This case details a patient with a ruptured aneurysm at the middle cerebral artery (MCA) bifurcation accompanied with seriously cerebral herniation successfully treated with the Woven EndoBridge (WEB) device placement via a distal transradial access. CASE PRESENTATION: A 51-year-old male Asian patient was admitted to Zhuhai People's Hospital due to a 6-hour consciousness impairment and left limb weakness. An emergency cranial computed tomography (CT) and computed tomography angiography (CTA) showed the patient had a ruptured aneurysm at the MCA bifurcation accompanied by a cerebral herniation. The Hunt-Hess grade was Ⅲ, the Glasgow Coma Scale (GCS) score was 9, and the National Institutes of Health Stroke Scale (NIHSS) score was 14. After obtaining informed consent from the family and discussing treatment options, the patient was successfully treated with the endovascular treatment by the WEB device placement via a distal transradial access. Intraoperative angiography showed complete deployment of the WEB in good position with aneurysm occlusion, achieving a Woven EndoBridge occlusion scale (WOS) grade of B. Subsequently, intracranial hematoma evacuation and decompressive craniectomy were immediately performed. At discharge, the patient scored 4 on the modified Rankin Scale (mRS). Six months and eighteen postoperatively, the patient returned for a follow-up examination with an mRS score of 1. Follow-up cranial CT showed absorption of the hematoma, and cerebral angiography confirmed complete aneurysm occlusion with a WOS grade of A.
conclusionsThis case demonstrates the technical feasibility of a combined strategy employing initial WEB embolization via distal transradial access followed by surgical decompression, for the management of a single patient with a critical ruptured middle cerebral artery aneurysm and cerebral herniation.
