Postoperative Lemierre's syndrome: a previously unreported complication of transoral surgery. Illustrative case.

BACKGROUND

Lemierre's syndrome is a rare but potentially life-threatening clinical condition characterized by bacteremia and thrombophlebitis of the internal jugular vein, usually secondary to oropharyngeal infection and often caused by Fusobacterium necrophorum; rarely, it occurs after surgical procedures. The most common clinical presentation includes acute pharyngitis, high fever, and neck pain. The diagnosis is based on blood culture and cranial and cervical spine computed tomography (CT)/magnetic resonance imaging (MRI) with contrast. Antibiotic therapy for 3-6 weeks is the mainstay of treatment, while the use of anticoagulant drugs is controversial.

OBSERVATIONS: The authors describe a case of Lemierre's syndrome that occurred after transoral surgery. The patient underwent a combined surgical approach from above (transoral) and below (anterolateral transcervical) to the upper cervical spine for the resection of a large anterior osteophyte causing dysphagia, globus sensation, and dysphonia. Three weeks after the surgical procedure, she developed fever and severe neck pain.

LESSONS: The aim of this paper is to consider Lemierre's syndrome as a possible complication after the transoral approach, underlining the importance of its early diagnosis and with a suggestion to perform cranial and cervical spine CT or MRI venous angiography in patients who undergo surgery with a transoral approach and exhibit local or systemic signs of infection such as neck pain, persistent fever, and positive blood culture results.
