[Exceptional medical circumstances: interest of an interhospital support strategy within the North Alps emergency trauma network].

The Northern French Alps Emergency Network (RENAU) has a main objective the improvement of the quality of the care in the field of the emergency medical treatment. With this French medical system, we developed a procedure allowing the detachment of a medical-surgical team of the university hospital to help general hospital team in the event of immediate vital emergency situation with untransportable patient. We reported the successful implementation of this support strategy for a 51-year-old patient arrived in a hospital of the network in extremely serious hemodynamic shock due to an important hemorrhagic pericardial effusion with tamponnade 1 day after percutaneous closure of the patent foramen ovale (PFO).
