Beskrivelse
Inclusion Criteria:
- Clinical and imaging diagnosis of liver cirrhosis and esophagogastric varices, with at least one previous episode of esophagogastric variceal bleeding
- Combined with portal vein thrombosis and D-dimer > 0.8mg/L
- Endoscopic evaluation reveals a high risk of variceal bleeding, and endoscopic treatment is performed to prevent rebleeding of esophagogastric varices
- Signed informed consent form
Exclusion Criteria:
- Received other antithrombotic therapies before (including warfarin, aspirin, low-molecular-weight heparin, etc.)
- Combined with hepatocellular carcinoma or other malignancy
- Combined with portal cavernoma
- Combined with severe life-threatening diseases of circulatory, hematological and respiratory system
- Combined with diseases requiring anticoagulant therapy, such as acute portal vein thrombosis, atrial fibrillation, lower extremity venous thrombosis, and pulmonary embolism
- Received TIPS or liver transplantation or splenectomy
- With contraindications to anticoagulant therapy (uncontrollable active bleeding, severe hepatic insufficiency, renal insufficiency, etc.)
- Currently taking immunosuppressive agents, or medications that affect cytochrome P450 (including azole antifungals and protease inhibitors), or strong inducers of CYP3A4 (including rifampicin, phenytoin, carbamazepine, etc.)
