[Prehospital thrombolysis of a pulmonary embolism with a severe shock].

The prehospital thrombolysis of a pulmonary embolism with high vital risk is not the subject of any recommendation. We report the case of a severe shock related to a suspicion of pulmonary embolism with favourable issue after the administration of a thrombolytic drug in prehospital conditions. The evolution's speed and the constraints of mobilization resulted in choosing an aggressive therapeutic strategy after evaluation of the benefit/risk ratio made only on the clinical data.
