Ultrasound guided microsurgical resection of cerebral arteriovenous malformations.
Article in Journal of cerebrovascular and endovascular neurosurgery, 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
objectiveMicrosurgical excision of intracranial arteriovenous malformations (AVMs) remains a surgical challenge that requires neurosurgical experience as well as neurosurgical tools. Advances in medical devices widen the range of tools that can be used to ensure patients' safety and procedural integrity. There is limited data published regarding the role of intraoperative ultrasound to ensure proper cerebral arteriovenous malformation excision.
methodsPatients who underwent ultrasound-assisted microsurgical excision of cerebral arteriovenous malformations were reviewed in a single center from 2021 through 2024. Patients' clinical, radiological, and intraoperative data were retrieved and analyzed.
resultsTwenty patients were included in the study. All lesions were in the cerebral regions. The study included 20 patients, 11 (55%) of whom were males and the patients' ages ranged from 5 to 55 years. Sixteen patients (80%) presented with headache, 13 patients (65%) with seizures, 8 patients (40%) with syncope, 2 patients (10%) with vomiting, and 6 patients (30%) with weakness.Thirteen patients (65%) had intracranial hemorrhage (ICH) on presentation. For all cases, intraoperative ultrasound (IOUS) was successful in confirming total resection of the lesion. In 13 cases that involved an intracerebral hematoma took place, the hematoma was visualized easily with grey-scale B-mode ultrasound, as well as its relation to the nidus was clearly delineated.
conclusionsIntraoperative ultrasonography is a useful, cost-effective, and non-invasive tool for guiding through cerebral arteriovenous malformation microsurgical excision.
