[A case of selective embolization in treatment of advanced tonsillar cancer hemorrhage]
Abstract:
This paper reports a case of recurrence of tonsillar cancer on the right 6 months after radiotherapy with pharyngeal hemorrhage for 4 days and aggravation in the next day. The pharyngeal hemorrhage was severe in the case and the maximum of single amount of bleeding was approximately 200 ml. The examination showed active bleeding on the ulcer with a diameter of 2 cm in the right tonsil and the depth of 1 cm. After repeated compression hemostasis proved to be invalid, selective embolization was applied on the patient and the symtoms of pharyngeal hemorrhage disappeared without complications. The patient was discharged after 2 weeks of observation without any recurrence of hemorrhage.
