Outcome Measures
Primary Outcomes (1)
Recanalization Rate
For each venous segment, the vein and residual patent lumen were outlined at the level of the maximum thrombosis. Total lumen area and patent lumen area were calculated with commercially available software. The degree of thrombus occlusion was estimated as a percentage by thrombosis area/total lumen area×100%. The primary outcome was the overall recanalization rate, both complete and partial. Complete recanalization was referred to the complete disappearance of the thrombus in the portal vein trunk, at least one of the two intrahepatic portal vein branches, SMV and SV. Partial recanalization was defined as a more than 50% reduction of the thrombus, with the thrombus not extending to other veins.

Secondary Outcomes (1)
Rate of Bleeding
6 months
Study Arms (2)
nadroparin calcium-warfarin sequential therapy group
EXPERIMENTALnadroparin calcium every 12 hours for 1 month followed by an oral administration of warfarin for 5 months
Control group
NO INTERVENTIONNo anticoagulation therapy.
Interventions
Nadroparin calcium subcutaneously every 12hs for 1 months followed by warfarin orally for 5 months. INR(international normalized ratio ) was detected every 3-4 days and adjusted carefully by 0.75mg dosage until achieve the target level of 2-3.
