Ascending aortic versus axillary artery cannulation in Stanford type A aortic dissection repair: a propensity score-weighted cohort study.

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
Background: Axillary artery cannulation is widely regarded as the preferred arterial inflow strategy for surgical repair of Stanford type A aortic dissection (TAAD). Ascending aortic cannulation has emerged as a practical alternative, yet comparative evidence on early outcomes and long-term survival remains limited. This study aimed to compare the early outcomes and long-term prognosis between these two arterial cannulation strategies. Methods: We retrospectively analyzed 160 patients who underwent surgery for TAAD at a single center between February 2017 and January 2025. Of these, 64 patients received axillary artery cannulation and 96 underwent ascending aortic cannulation. Early postoperative outcomes and long-term survival were assessed using inverse probability of treatment weighting (IPTW) and Kaplan-Meier survival curves. Results: Before adjustment, 30-day mortality was higher in the axillary than the ascending aortic cannulation group (9.4% Conclusions: In this single-center propensity score-weighted cohort, ascending aortic cannulation was associated with lower short-term mortality and fewer postoperative complications compared with axillary cannulation. Mortality and long-term survival differences favored ascending aortic cannulation numerically but were attenuated after IPTW, underscoring the need for larger prospective studies to confirm these findings.
