へん桃周囲膿ように合併した外頚静脈血栓例

Abstract

Venous thrombosis is rare in the head and neck region, and although some cases of internal jugular vein thrombosis secondary to oropharyngeal infection, central venous catheter and neoplasm have been reported in the literature, there have been few reports on cases of external jugular vein thrombosis. We report here a case of external jugular vein thrombosis secondary to peritonsillar abscess in a 65-year-old man who was admitted to our hospital with a 2-week history of severe sore throat, high fever, trismus, parotid swelling, left neck swelling and pain. CT scan revealed left peritonsillar abscess and left external jugular vein thrombosis between the infratemporal fossa and supraclavicular fossa. The patient was treated with antibiotics and surgical drainage of peritonsillar abscess, but the swelling and pain of the left neck due to external jugular vein thrombosis persisted. Ligation and resection of the left external jugular vein was performed and the symptoms disappeared after surgery. We speculated that the external jugular vein thrombosis in this case was secondary to the peritonsillar abscess. Considering the history of trismus and parotid swelling, the inflammation of the peritonsillar abscess may have extended to the parapharyngeal space, mainly the prestyloid compartment, and caused thrombophlebitis of the retromandibular vein in the parotid gland.
