Pseudoaneurysms as a complication of stereoelectroencephalography: Case series and clinical recommendations.

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
objectiveStereoelectroencephalography (sEEG) is commonly employed in the workup for epilepsy surgery in patients with focal drug-resistant epilepsy (DRE). Intracranial hemorrhage is a known complication, with reported incidence rates ranging from .9% to 19.1%. Rarely, pseudoaneurysms have been reported in literature as a potential cause. This retrospective cohort study aims to describe the occurrence, clinical characteristics, and management of iatrogenic pseudoaneurysms following sEEG and the clinical outcome of the described cases.
methodsA cohort of 395 patients (4067 depth electrodes) with DRE who underwent sEEG was retrospectively analyzed. The identified patients with pseudoaneurysms were analyzed in detail, focusing on timing of detection and location of the aneurysms, clinical characteristics, management strategies, and clinical outcome.
resultsA symptomatic iatrogenic pseudoaneurysm was identified in six of 395 cases (1.5%), with a per-electrode risk of .15% (6/4067); all occurred at the M2/M3 branches of the middle cerebral artery. All six cases presented with intracerebral or subarachnoid hemorrhage. Aneurysms were detected with combined cerebral computed tomographic angiography (CTA) and digital subtraction angiography (DSA) and treated without complications by surgical clipping or endovascular embolization. The depth electrode implantation and planned sEEG recording had to be either prematurely discontinued or canceled in four of six cases. No patients died; five experienced neurological symptoms and required prolonged hospitalization, with four needing additional rehabilitation. SIGNIFICANCE: Pseudoaneurysms following sEEG represent a serious complication with significant clinical consequences and warrant early detection and intervention. Occurrence is underreported in literature. It is recommended to use CTA and DSA when a pseudoaneurysm is suspected, particularly in cases of intraparenchymal or subarachnoid hemorrhage, and especially when depth electrodes are in close proximity to a blood vessel.
