Calcium in the (Big) Pipes: Intra-TEVAR Calcifications!
Article in EJVES vascular forum, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Introduction: Calcification of a vascular endograft and adjacent tissues (adventitia, media, and neointima) can result in graft failure. This report shows a rare case of intraluminal calcifications in the distal end of a thoracic endovascular aortic repair (TEVAR) endograft implanted 11 years previously for grade IV blunt traumatic aortic injury (BTAI) in a young patient. Report: A 24 year old man required TEVAR for a BTAI caused by a motorcycle accident. The procedure consisted of TEVAR and an emergency left carotid subclavian venous bypass. Eleven years after the procedure, he had severe hypertension. Intra-TEVAR calcifications appeared, gradually increasing on computed tomography angiography (CTA). Calcifications in the distal luminal end of the TEVAR were responsible for a 60% stenosis on CTA. An open approach was indicated after multidisciplinary discussion, based on the gradient value. The patient underwent explantation, with total replacement of the aortic arch and descending thoracic aorta with re-implantation of the supra-aortic vessels, under extracorporeal circulation. Macroscopic analysis showed no device degeneration but revealed a solid mass at the distal end of the TEVAR. Both microcomputed tomography and histopathology confirmed the calcific nature of the lesions. Conclusion: This case highlights a rare long term graft failure due to calcified neo-atherosclerosis in a TEVAR.
