Preoperative extracorporeal membrane oxygenation is associated with improved outcomes in emergent surgical pulmonary embolectomy.

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
objectivesThe impact of preoperative veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support on outcomes of emergent pulmonary embolectomy for acute pulmonary embolism (PE) remains unclear. This study evaluated the safety and efficacy of preoperative VA-ECMO in patients undergoing emergent surgical embolectomy for high-risk PE.
methodsBetween December 2007 and September 2025, 38 consecutive patients underwent emergent pulmonary embolectomy for acute PE. Patients were divided into two groups: without preoperative VA-ECMO (Group A, n = 17) and with preoperative VA-ECMO (Group B, n = 21). The primary outcome was a composite of in-hospital mortality and cardiopulmonary arrest (CPA) during anesthesia induction. Secondary outcomes included postoperative complications and long-term survival. Kaplan-Meier analysis was used to compare survival.
resultsBaseline characteristics were comparable between groups. Four patients in Group A (23.5%) experienced the primary outcome versus none in Group B (0%, p = 0.032). In-hospital mortality was 17.7% in Group A versus 0% in Group B (p = 0.081). Postoperative complications were similar between groups. The mean follow-up period was 55.0 ± 50.1 months. Five-year overall survival was significantly lower in Group A (62.4%) than in Group B (94.4%, log-rank p = 0.012).
conclusionsPreoperative VA-ECMO support was safe, and was associated with a lower incidence of hemodynamic collapse during anesthesia induction and better early and long-term survival. Consideration of preoperative VA-ECMO support should be given to improve early and long-term survival.
