Abstract
Pylephlebitis refers to the septic thrombosis of the portal vein and its branches due to an infectious focus at the intra-abdominal level. Among the most frequent etiologies we can find diverticulitis, appendicitis and cholangitis. It can also be associated with hypercoagulable states, neoplasms and deficiency of coagulation factors. The treatment focuses on the eradication of the infectious focus through antibiotic therapy and in the prevention of its extension and mesenteric ischemia through anticoagulation. We describe the case of a patient with a history of acute appendicitis that develops septic thrombosis of the portal vein, splenic vein and superior mesenteric vein.
