A case of internal jugular vein thrombophlebitis induced by carotid sheath abscess caused by odontogenic infection

Abstract

We describe our experience with a case of deep neck abscess induced by periodontitis of the mandibular canine tooth with internal jugular vein thrombophlebitis.

　A 77-year-old woman was referred to our hospital because of swelling of the right cheek. Computed tomography (CT) revealed gas bubbles and abscesses from the infratemporal fossa to the lower pole of the thyroid, especially in the retrovisceral space and carotid sheath. The patient was immediately hospitalized to control the infection. We performed a surgical incision and drainage of the abscess to reduce inflammation, and antibiotics were given for 44 days. Moreover, internal jugular vein thrombophlebitis arose from an extended carotid sheath abscess on hospital day 7. We therefore additionally administered anticoagulant therapy. The thrombophlebitis disappeared on hospital day 51. All symptoms improved, and she was discharged after 85 days.
