Trombose van de V. portae: oorzaken en behandeling

- Portal vein thrombosis (PVT) has a heterogeneous aetiology. Recently discovered thrombotic risk factors such as latent myeloproliferative disorders and prothrombotic genetic defects are important in the aetiology of PVT. At least one-third of the PVT patients exhibit a combination of thrombotic risk factors.

- Treatment with anticoagulant drugs has not proved beneficial for most PVT patients. Therapy with anticoagulants is only recommended in those with acute PVT, in those who recently underwent a portosystemic shunt procedure and in those with other thrombotic manifestations, particularly in case of proved hypercoagulability.

- Due to intact coagulation, oesophageal varices bleeding in patients with PVT has a better prognosis than in cirrhotics.
