Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In case of acute portal vein thrombosis (PVT) prothrombotic factors are identified in about 60% of cases, while a local condition is present in 30% of cases. Prothrombotic factors may indicate a long term anticoagulant therapy whereas the risk of recurrence seems low when a local condition is isolated (cholecystitis, angiocholitis, liver abces, diverticulitis, appendicitis, acute/chronic pancreatitis, chronic bowel inflammatory disease, acute hepatitis due to cytomegalovirus, bacteroïdes pylephlebitis, abdominal neoplasia such as adenocarcinoma of the colon, abdominal traumatism or surgery such as cholecystectomy, bariatric surgery or splenectomy). To date the impact of prothrombotic factors associated with local conditions responsible for acute PVT has not been well studied except for acute or chronic pancreatitis. No significant association has been pointed out in this pathology. The aim is to determine what are the risk factors of thrombotic recurrence or extension associated with local conditions responsible for acute non cirrhotic PVT, and to evaluate the rate of secondary long term anticoagulant therapy.
