Portal Vein Thrombosis Current guidelines in Beaujon

→ Permanent anticoagulation

No contraindication

Prophylaxis for PHT-related bleeding

Permanent prothrombotic disorder

Anticoagulation for BCS

Janssen et al, J Hepatol 2003. de Franchis, J Hepatol 2005.

• Anticoagulation recommended to all patients, in the absence of major contraindication.

• Previous bleeding from portal hypertension is not considered a major contraindication, provided appropriate prophylaxis for recurrent bleeding is initiated.

Conclusions

• Blood disorders are major causes of vascular liver diseases.

• Atypical myeloproliferative diseases most commonly implicated.

• Frequent combination of several causes.

• Permanent anticoagulation is generally recommended once prophylaxis for portal hypertensive bleeding has been instituted.
