Dear Audrey, dear colleagues,
We have here a patient with INCPH and a thrombus that occurred at a period well known to be procoagulant (postpartum). She has been treated with anticoagulation for 1 year. At the stage we are now, there is no data supporting one attitude (no anticoagulation) or the other (anticoagulation). In situations at risk (pregnancy, hospitalization, etc) anticoagulaion is likely needed.
If anticoagulation is discontinued, I would personally (extrapolating on data from Delgato CGH 2012 obtained in cirrhosis and our local experience on PVT) propose an ultrasonography at 1 and 3 months and a CT scan at 6 month. I thrombosis recurs, then anticoagulation is clearly needed on the long term.
