Mesenteric vein thrombosis (MVT) is a rare condition, often misdiagnosed due to its vague and misleading clinical presentation. It can cause intestinal infarction, peritonitis, and consequently necessitate bowel resection. CT scanning with intravenous contrast enhancement is the gold standard for its diagnosis. Radiologists have an important role in defining the extent of thrombosis and identifying any signs of intestinal infarction influencing the decision whether or not to operate. In patients with no clinical signs of peritonitis or radiological evidence of intestinal infarction, the treatment can be exclusively medical, based on full anticoagulation (initially with low molecular weight heparin, followed by vitamin K antagonists or direct acting oral-anticoagulants). The duration of medical treatment depends on radiological evidence of resolution of thrombosis and the identification of pro-coagulant risk factors.

Abstract

Mesenteric vein thrombosis (MVT) is a rare condition, often misdiagnosed due to its vague and misleading clinical presentation. It can cause intestinal infarction, peritonitis, and consequently necessitate bowel resection. CT scanning with intravenous contrast enhancement is the gold standard for its diagnosis. Radiologists have an important role in defining the extent of thrombosis and identifying any signs of intestinal infarction influencing the decision whether or not to operate. In patients with no clinical signs of peritonitis or radiological evidence of intestinal infarction, the treatment can be exclusively medical, based on full anticoagulation (initially with low molecular weight heparin, followed by vitamin K antagonists or direct acting oral-anticoagulants). The duration of medical treatment depends on radiological evidence of resolution of thrombosis and the identification of pro-coagulant risk factors.
