Carotid hemorrhage: a complication of peritonsillar abscess

Carotid hemorrhage secondary to peritonsillar abscess occurs infrequently today because of the effectiveness of antibiotic therapy. When it does occur, however, emergency physicians unfamiliar with such a complication may have difficulty making its diagnosis and instituting appropriate therapy. Prevention is the easiest way to treat septic erosion. Abscesses are treated best with penicillin or, in the allergic patient, clindamycin followed by incision and drainage. Once the abscess has eroded into the carotid artery, it usually must be tied off to control the subsequent massive bleeding.
