A case of epistaxis.

The authors report a case of epistaxis in a 74-year-old male patient. His recent medical history documented recurrent nasal bleeding and a Le Fort 1 osteosynthesis 3 weeks before admission to our unit. A CT scan revealed a left descending palatine artery pseudoaneurysm in the left maxillary sinus that was successfully embolized. Pseudoaneurysms of the internal maxillary artery and its branches are rare life-threatening complications. This diagnosis should be considered when confronted to recurrent head and neck bleeding, especially in a context of recent maxillo-facial trauma or surgery. Embolization should rapidly be implemented.
