We report the case of a man with a massive pulmonary embolism, which lead to cardiac arrest. After ruptured aneurysm clipping, he was successfully treated by rescue thrombolysis administered as compassionate treatment despite the risk of cerebral bleeding. The patient was discharged from the intensive care unit; his initial neurological, cardiac, and pulmonary conditions restored. In case of life-threatening pulmonary embolism, the risk-benefit ratio of thrombolysis therapy should be systematically evaluated and the decision adapted to each patient.
