Mimicking aneurysm in a patient with chronic occlusion of the left middle cerebral artery: A case report.
Article in World journal of clinical cases, 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
backgroundWith the popularization of various cerebrovascular imaging methods and increased attention to the field, more cerebrovascular diseases are being detected in asymptomatic patients. Different cerebrovascular diseases are typically isolated but occasionally occur simultaneously, causing difficulties in diagnosis and treatment. Morphological changes in the collateral circulation of blood vessels in chronic cerebral artery occlusion patients are slow and dynamic, intercepting morphological development at a specific moment. Excessive reliance on single imaging tests such as digital subtraction cerebral angiography (DSA) can lead to misdiagnosis. CASE SUMMARY: We report a 52-year-old male who was admitted to our department for treatment of an unruptured aneurysm during a follow-up examination for brain trauma after 1 mo. Computed tomography (CT) scan was negative, but CT angiography (CTA) revealed a sac-like bulge at the bifurcation of the left middle cerebral artery. DSA revealed an unruptured aneurysm with unique scapular morphology. The stump of a middle cerebral artery occlusion was observed during exposure during aneurysm clipping surgery, and the diagnosis of chronic cerebral artery occlusion was confirmed intraoperatively. This case was confusing because of the peculiar morphology of the arterial stump and compensatory angiogenesis due to multiple cerebral artery stenoses observed on preoperative CTA and DSA. The surgery did not cause secondary damage to the patient, and medical treatment for risk factors was continued postoperatively.
conclusionMultiple cerebral arterial stenoses can occur in conjunction with aneurysms or arteriovenous malformations, and their unique morphology can lead to misdiagnosis.
