Abstract    Due to the hidden symptoms of mesenteric venous thrombosis (MVT)，it is easy to delay the diagnosis resulting in high mortality. Careful inquiry of thrombosis risk factors combined with imaging examination, especially the vascular Doppler and CTA，can help to diagnose early. After diagnosis of MVT，systemic anticoagulant therapy should be administered immediately. For patients with peritonitis and intestinal necrosis，emergency resection of necrotic bowel should be performed. If anticoagulant therapy is invalid，or even lead to exacerbation of symptoms，thrombolytic treatment of thrombosis site should be chosen by vascular intervention technique if no contraindication exists，so as to promote the recovery of mesenteric and portal venous circulation.
