Four-Dimensional Computed Tomography Differentiates Congenital Right Pulmonary Vein Atresia From Suspected Arteriovenous Malformation: 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
Congenital pulmonary vein atresia (PVA) is a rare condition often associated with vascular anomalies and complex pulmonary hemodynamics. A 54-year-old woman was referred for evaluation of a nodular shadow in the right upper lobe, initially suspected to represent a pulmonary arteriovenous malformation (PAVM). Four-dimensional enhanced computed tomography (4D-CT) revealed no abnormal vessels, suggesting a PAVM in the pulmonary arterial phase. However, in the venous phase, the pulmonary vein of the right upper lobe was occluded at the trunk, with reflux via a pulmonary vein varix and an abnormal vein draining into the pulmonary vein of the right middle lobe. Due to the risk of pulmonary hypertension, thromboembolism, or varix rupture, the patient underwent right upper lobectomy. 4D-CT effectively delineates the vascular morphology by separating the pulmonary arterial and venous phases. Congenital PVA may involve pulmonary vein varices and abnormal vascular formation; 4D-CT may be valuable for diagnosis and treatment planning.
