Diagnostic pitfalls of computed tomography angiography in high-energy knee trauma: two case reports on complete popliteal artery transection despite preserved distal flow.

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
This report describes two rare cases of complete popliteal artery transection in young, previously healthy men following high-energy trauma. In both cases, computed tomography (CT) angiography demonstrated a segmental arterial defect with preserved distal flow and no contrast extravasation, resulting in a delayed or uncertain diagnosis. These cases underscore the importance of incorporating the mechanism of injury into clinical decision-making. Both patients exhibited neurologic deficits in the affected limbs. Physical examination revealed signs of ischemia and sensorimotor dysfunction. Despite discordant CT findings, surgical exploration confirmed complete arterial transection in both cases, necessitating vascular reconstruction. In cases of high-energy knee trauma, surgical exploration should be considered when clinical findings suggest neurovascular compromise, even if CT angiography demonstrates preserved distal flow.
