ABSTRACT
Suppurative thrombophlebitis of the portal-mesenteric venous system occurring in the setting of abdominal inflammatory and infectious processes is a serious condition that can lead to septic shock, bowel ischemia, hepatic abscess, and death if unrecognized. Diagnosis is often delayed because symptoms are aspecific and pain at the primary site of infection may be mild. Contrast-enhanced CT scans can diagnose both portal thrombosis and a primary infection site. Treatment may include early resective surgery in case of appendicitis or diverticulitis, in association with large-spectrum antibiotics and possibly anticoagulation. A characteristic of suppurative thrombophlebitis, whether splanchnic or systemic, is the latency before the effects of antibiotic therapy are seen. Anticoagulation can be administered to avoid extension to the superior mesenteric vein. We presented a critically ill 53-year-old man with chronic colonic diverticulitis complicated by suppurative emphysematous portal-mesenteric thrombophlebitis with only a slow response to large-spectrum antibiotics.
