Successful treatment of acute symptomatic extensive portal venous system thrombosis by 7-day systemic thrombolysis.

Acute portal venous system thrombosis (PVST) can cause acute mesenteric ischemia and even intestinal infarction, which are potentially fatal, and requires recanalization in a timely fashion. Herein, we report a 56-year-old man with acute non-cirrhotic symptomatic extensive PVST who achieved portal vein recanalization after systemic thrombolysis combined with anticoagulation. Initially, anticoagulation with enoxaparin sodium for 4 d was ineffective, and then systemic thrombolysis for 7 d was added.
