A case of contrast-induced encephalopathy after thoracic endovascular aortic repair for a ruptured thoracic aortic aneurysm.

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
backgroundContrast-Induced Encephalopathy (CIE) is a rare complication, most commonly reported after carotid or coronary interventions, possibly due to reporting bias. CASE PRESENTATION: We present a case of CIE following two-debranching thoracic endovascular aortic repair (TEVAR). A 79-year-old man with hypertension, hyperlipidemia, stage 4 chronic kidney disease (CKD), and prior cerebral infarction underwent emergency 2-debranching TEVAR for a ruptured thoracic aortic aneurysm (TAA). A total of 200 mL of contrast medium was used pre- and intraoperatively. On postoperative day (POD) 1, the patient remained unconscious despite sedation cessation. Non-contrast brain Computed tomography (CT) showed left hemispheric cerebral edema and high-density areas suggestive of contrast extravasation, raising suspicion for CIE. Conservative management with hydration and supportive care led to gradual recovery, with imaging on POD9 showing near-complete resolution.
conclusionsAlthough rare, CIE should be considered in cases of delayed consciousness recovery after TEVAR, particularly in high-risk patients. Early diagnosis and conservative treatment are essential for good outcomes.
