Perioperative severe airway hemorrhage during veno-arterial extracorporeal membrane oxygenation for acute massive pulmonary embolism: A case report.
Article in Medicine, 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
rationaleAccording to the 2019 ERS/ESC guidelines, high-risk pulmonary embolism is defined as a case that presents with hemodynamic instability, obstructive shock, or cardiac arrest, and this condition has an extremely high death rate. ECMO can provide temporary circulatory support, acting as a bridge to definitive reperfusion therapy. PATIENT CONCERNS: The patient is a 25-year-old woman who had previously used estrogen-containing oral contraceptives. She sustained trauma to her right lower limb, necessitating prolonged immobilization. One month before her symptoms started, she had a high fever. One hour before she was admitted to the hospital, she fainted and went into cardiac arrest. Ten minutes of cardiopulmonary resuscitation were needed before her spontaneous circulation returned. DIAGNOSES: The electrocardiography test showed an S1Q3T3 pattern. An ultrasonography check confirmed thrombosis in the right popliteal vein. Transthoracic echocardiography found that the right heart was enlarged, and the left ventricle had a D shape. Computed tomography pulmonary angiography showed a saddle embolus right at the bifurcation of the pulmonary artery, which confirmed acute massive pulmonary embolism (MPE).
interventionsThe patient was supported with veno-arterial extracorporeal membrane oxygenation (VA-ECMO), followed by catheter-directed thrombolysis and targeted airway hemostasis. Urokinase was administered through 2 thrombolysis catheters, and anticoagulation was adjusted dynamically according to bleeding and coagulation status. OUTCOMES: After the procedure, airway bleeding was stopped using targeted hemostasis methods, and the patient was able to come off ECMO successfully after 73 hours of use. LESSONS: In this case, we achieved successful support from VA-ECMO for a patient with acute MPE. Our work shows that even severe bleeding in the airway can be handled safely, and you don't have to stop anticoagulation treatment to do it. This approach ended up with the patient making a full recovery in the end.
