Outcome Measures

Primary Outcomes (1)

  • Recanalization rate of PVT

    Patients will receive Doppler ultrasound and CT before enrolled and followed up by Doppler ultrasound every 3 months ,by CT every 6 months after enrolled,untill the end of the study.

    through study completion,an average of 18 months

Secondary Outcomes (2)

  • Rebleeding rate

    through study completion,an average of 18 months

  • Incidence rate of complications

    through study completion,an average of 18 months

Study Arms (2)

Control.

OTHER

No anticoagulation,just routine follow up.

Device: Doppler ultrasound and CT

Anticoagulation

EXPERIMENTAL

Nadroparin Calcium and Warfarin

Drug: Nadroparin Calcium and WarfarinDevice: Doppler ultrasound and CT

Interventions

Patients will take warfarin started at a dose of 2.5mg/d and with titration of dose to maintain a target INR of 2-3, and during the of perioperative period of Endoscopic treatment changing to use Nadroparin Calcium 4100IU/d,subcutaneous.

Anticoagulation

all patient will take Doppler ultrasound examination every 3 months ;Abdominal CT will be done every 6 months。

AnticoagulationControl.
