Stroke and refractory hypoxaemia: complications of pulmonary embolism.

Acute pulmonary embolism is one of the main causes of cardiovascular mortality. Treatment should be guided according to mortality risk stratification, but an individualised and multidisciplinary approach is often required. Concomitant persistent hypoxaemia can be present in cases of intracardiac shunt. In this report, we describe a 46-year-old woman with a history of surgery, presenting with pulmonary embolism with refractory hypoxaemia and simultaneous ischaemic stroke. Fibrinolysis was successfully performed, and the patient made a full recovery. Additional investigations identified a patent foramen ovale, which was later closed. She had no recurrent thrombotic events.
