[Sublingual haematoma: an unusual complication of oral anticoagulation therapy: about one case]. / Hématome sublingual : complication inhabituelle du traitement anticoagulant oral: à propos d'un cas.

Bleeding complications of oral anticoagulant therapy are not rare. The locations for bleeding are most often gastrointestinal, genitourinary and intracranial. Upper airway obstruction remains one of the reported complications. It is produced in most cases by a retropharyngeal haematoma. On the other hand, sublingual haematoma is exceptional and constitutes a problem to secure patient's airway. We report the case of a 16-year-old patient, admitted tenhours after accidental ingestion of 40mg of Sintrom((R)) with major breathing difficulty, haemoptysis and epistaxis. The endotracheal intubation was performed blindly using an Eschmann candle. This rare complication should be prevented by an adapted clinical and biological monitoring.
