Pylephlebitis: A Rare Complication of Acute Appendicitis.

Pylephlebitis is defined as an infective suppurative thrombosis of the portal vein and its tributaries - a rare complication of intra-abdominal infections. It is most commonly seen in patients with diverticulitis and appendicitis. Prompt diagnosis with abdominal ultrasound and computerized tomography (CT) scan along with early and aggressive treatment with broad-spectrum antibiotics is crucial because of its high mortality rates. However, this diagnosis is often missed due to the nature of its nonspecific clinical symptoms. We discuss a case of a 22-year-old male who presented with pylephlebitis as a complication of acute gangrenous appendicitis. The patient was treated successfully with appropriate surgical intervention, antibiotics, and anticoagulation.
