Oxygenator salvage with low-dose thrombolysis. Case report.
Article in Journal of artificial organs : the official journal of the Japanese Society for Artificial Organs, 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
Membrane oxygenator exchange can be a frequent requirement during extracorporeal membrane oxygenation (ECMO). In low-income health systems, the scarcity and cost of disposables pose significant challenges to timely exchanges. We describe a 48-year-old woman placed on veno-venous ECMO for refractory hypoxemic respiratory failure secondary to pneumonia. Within 30 min, the oxygenator developed thrombosis, characterized by a transmembrane pressure gradient of 229 mmHg. A total of 10 mg of recombinant tissue plasminogen activator (rt-PA) was administered through the premembrane port. Sixty minutes after infusion, the gradient decreased to 116 mmHg, with subsequent improvement in oxygenation. No bleeding occurred. The patient was successfully weaned from ECMO and discharged from the ICU without complications. Low-dose rtPA instillation into a failing oxygenator can postpone exchange and represents a viable salvage strategy for resource-limited ECMO programs.
