INTRODUCTION
Superior mesenteric vein thrombosis (SMVT) caused by acute appendicitis is a very rare
entity. It may cause varying degrees of intestinal wall lesions as oedema, congestion,
and eventually necrosis. It is essential to make an early diagnosis, although its non-specific
clinical presentation, so as to initiate specific treatment as soon as possible to avoid fatal
outcome. Indeed, the mortality rate of SMVT associated with intra-abdominal infection is
relatively high and ranges from 30 to 50% [1] .
