A rare subclavian artery aneurysm potentially misidentified as the internal jugular vein in ultrasound-guided central venous catheterization -a case report.

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
backgroundCentral venous catheterization by anesthesiologists carries risks such as accidental arterial puncture. This case report highlights a rare subclavian artery aneurysm (SAA) detected during ultrasound-guided internal jugular vein (IJV) access, emphasizing the importance of recognizing anatomical variations. CASE: An 88-year-old female with hypertension and atrial fibrillation was scheduled for lumbar laminectomy and posterior fusion. Preoperative evaluation revealed right lower lobe atelectasis and mild aortic sclerosis. During ultrasonography for right IJV catheterization, two vessels of different diameters were observed on the common carotid artery's lateral side. The larger vessel disappeared at the upper neck level, showing arterial pulsation on Color Doppler. Postoperative neck computed tomography confirmed a right SAA and a 5-mm saccular aneurysm in the left intracranial artery. The patient had no vascular disease, trauma, or relevant family histories.
conclusionsAnesthesiologists should be aware of anatomical variations during IJV catheterization. Ultrasound with Doppler is crucial for accurate artery identification.
