A Case of Primary Mesenteric Venous Thrombosis Presenting with Acute Abdominal Pain

ABSTRACT

Mesenteric venous thrombosis (MVT) is a rare, but lifethreatening condition and may induce ischemia or necrosis of small intestine. The predisposing factors of MVT are variable and include previous abdominal surgery, a hypercoagulable state, etc. When no possible predisposing factors exist, we call it primary MVT. A 29-year-old man was presented with upper abdominal pain and was diagnosed as having a MVT by using an abdominal computed tomography scan. The protein C and S levels were decreased at the ED, but were normal on the 49th hospital day. We did not find any predisposing factors, so we classified this patient as having primary MVT. We report this case along with a literature review.
