Safety and feasibility of aortic crossclamp for thrombosed acute type A aortic dissection.
Article in JTCVS open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Aortic crossclamping in acute type A aortic dissection surgery facilitates proximal procedures during systemic cooling and reduces cardiopulmonary bypass time. However, concerns exist about embolization risk when crossclamping patients with thrombosed false lumen. We compared safety and feasibility of ascending aortic crossclamping between thrombosed and patent false lumen in acute type A aortic dissection. Methods: This single-center retrospective study analyzed 1550 consecutive acute type A aortic dissection patients undergoing surgery between January 2004 and December 2023. Of these, 1407 patients completed aortic crossclamping and were divided into thrombosed false lumen (400 patients [28.4%]) and patent false lumen (1007 patients [71.6%]) groups. Propensity score matching yielded 400 matched pairs. Results: After propensity score matching, both groups showed similar preoperative characteristics. No significant differences existed in new onset ischemic stroke (5.8% vs 5.5%; Conclusions: Ascending aortic crossclamping was safe and feasible in acute type A aortic dissection surgery regardless of false lumen status. Thrombosed false lumen presence does not increase neurological complications or early mortality risk.
