Characteristics of a Pure Acute Subdural Hematoma Caused by Intracranial Aneurysm Rupture: A Case Report and Review of Literature.
Article in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Pure acute subdural hematomas (ASDHs) due to ruptured aneurysms without subarachnoid or intracerebral hemorrhage are rare. We report the case of a 26-year-old female who presented with a pure ASDH caused by a ruptured distal anterior cerebral artery (ACA). The patient complained of sudden headache and vomiting and was transferred to our hospital. On the ambulance journey to the hospital, her consciousness level decreased suddenly just after experiencing additional pain in the head. At admission, the consciousness level was 4 points on the Glasgow coma scale with bilateral pupil dilatation. Computed tomography (CT) and CT angiography showed a left ASDH without subarachnoid hemorrhage (SAH) and a distal ACA aneurysm. Emergent hematoma evacuation was performed, but SAH and the bleeding point were not observed. Therefore, coil embolization for the distal ACA aneurysm was performed after an emergent operation. During embolization, intraoperative rupture was observed. The contrast media was seen up to the convexity subdural space along the falx. Extravasation ceased after intraaneurysmal coil embolization. Consequently, the rupture of the distal ACA aneurysm was diagnosed as the cause of the pure ASDH. The patient received additional coil embolization due to recanalization of the aneurysm without rebleeding 44 days after admission and was transferred to a rehabilitation hospital 55 days after admission to our hospital with a score of 4 on the modified ranking scale. From the reviews of 56 patients from 32 studies, including our case, we determine that an ACA aneurysm could show the distant hematomas located far from the site of a ruptured aneurysm compared with a ruptured aneurysm located in the internal carotid and middle cerebral arteries. Distant hematoma location could also lead to delayed diagnosis of aneurysms and lead to rebleeding and poor outcomes. Aneurysm rupture diagnoses should receive special attention, especially for ACA aneurysms, as the hematoma may be located far from the rupture site.
