Pylephlebitis: An uncommon complication of sigmoid diverticulitis

Abstract

Pylephlebitis is defined as a septic thrombophlebitis of the portal vein, usually secondary to infection in regions contiguous to or drained by the portal system. Although extremely uncommon in the modern era, pylephlebitis still carries an appreciable risk of severe morbidity and mortality, if unrecognized and left untreated. Herein we report the case of severe pylephlebitis in a patient with acute sigmoid diverticulitis. Although highly elusive, prompt diagnosis is crucial to ensure appropriate management and limit associated morbidity.
