[Anticoagulation in a patient with Lemierre syndrome and pulmonary septic embolisms].

Lemierre's syndrome, also called septic thrombophlebitis of the internal jugular vein, necrobacillosis or postanginal sepsis, is an infection that begins in the oropharyngeal space, is complicated by septic thrombophlebitis of the internal jugular vein and infectious metastases. The rapid progression to serious clinical conditions that compromise the patient's life and its low frequency justify the disclosure of clinical cases. We present the case of a 27-year-old woman who developed facial edema and trismus 48 hours after completing treatment with phenoxymethylpenicillin for an odontogenic infection. An angio-CT of the craniofacial massif revealed an extensive thrombus in the internal jugular vein and a computed tomography of the chest showed septic pulmonary emboli. Treatment consisted of broad-spectrum intravenous antibiotics and early anticoagulation.
