Successful Treatment Of Acute Portal Vein Thrombosis Extending To Superior Mesenteric Vein With Low-Molecular-Weight Heparins: A Case Report

Portal vein thrombosis (PVT) is a rarely but potentially life- threatening disease that usually occurs in the extrahepatic portal vein (PV). Further extension to the splenic and superior mesenteric vein (SMV) causes intestinal infarction with a high mortality exceeding 50%. PVT needs individual and timely treatment, including anticoagulation, thrombolysis, surgical thrombectomy, insertion of shunts, bypass surgery, or liver transplantation in different case. Here, we present a case of acute PVT after the rectal surgery who was early diagnosed and successfully cured by low-molecular-weight heparins (LMWH) with completely asymptomatic and recanalization of the PV and SMV.
