Abstract:A 66-year-old Japanese woman developed pulseless electrical activity following an acute pulmonary embolism and was treated with thrombolytic therapy. She remained hemodynamically unstable and therefore underwent extracorporeal membrane oxygenation (ECMO). While receiving treatment with ECMO, blood clots induced by endobronchial hemorrhage caused tracheobronchial airway obstruction, leading to ventilatory defect. Furthermore, her cardiac function improved, resulting in cerebral hypoxemia progression. Therefore, the blood clots were removed with a Fogarty balloon catheter and endobronchial urokinase administration, resulting in improvement in her respiratory condition. Finally, ECMO was decannulated, and the patient was discharged from our hospital without difficulties in her activities of daily living.
Keywords:acute pulmonary embolism  extracorporeal membrane oxygenation  tracheobronchial obstruction
