Septic thrombophlebitis of the portal and superior mesenteric veins as a complication of appendicitis: report of a case.

Pylephlebitis is extremely rare and associated with high mortality, even in this modern era. It usually occurs secondary to infection in the region drained by the portal systems or in the structure contiguous to the portal vein. We report a case of septic thrombophlebitis of the portal and superior mesenteric veins (SMV) with multiple liver abscesses caused by acute appendicitis with an abscess of the mesoappendix. We performed appendectomy and successfully removed the thrombi using a Fogarty catheter. Postoperative histopathological examination confirmed a diagnosis of appendicitis and septic thrombophlebitis of the portal vein and SMV. The patient recovered completely with appropriate medical and surgical treatment.
