A pilot study of safety and efficacy comparison of low molecular heparin calcium sequential oral anticoagulants in the treatment of cirrhotic portal vein thrombosis

Study on Anticoagulant Treatment for Portal Vein Thrombosis in Cirrhosis Patients

Objective

To compare the safety and effectiveness of two anticoagulant treatments for portal vein thrombosis (PVT) in cirrhosis patients.

Methods

Cirrhotic patients with PVT received low-molecular-weight heparin calcium (LMWH-Ca) injections for 2 weeks. They were then randomly assigned to receive either warfarin or rivaroxaban for a specified duration. Volumetric changes in PVT were monitored using computed tomography scans.

Results

Rivaroxaban treatment significantly reduced PVT volume and prevented worsening, while warfarin treatment led to an increase in PVT volume. Rivaroxaban also showed a lower incidence of gastrointestinal bleeding compared to warfarin.

Conclusion

Rivaroxaban followed by LMWH-Ca is an effective anticoagulant treatment strategy for PVT in cirrhosis.
