edoxaban and Liver-Cirrhosis

Cirrhosis-associated portal vein thrombosis (CA-PVT) has been reportedly observed in 5-30% of cirrhotic patients. Moreover, the acute exacerbation of CA-PVT is likely to occur after certain situations, such as a status after abdominal surgery. Safety and efficacy of the direct-acting oral anticoagulant (DOAC) used for cirrhotic patients have been being confirmed. However, use of the DOAC as an initial treatment for CA-PVT appears still challenging especially in the early postoperative period after major surgery in terms of unestablished efficacy and safety in such occasion.. We herein report a case of the acute exacerbation of CA-PVT in the early postoperative period after abdominal surgery, which was successfully treated with DOAC, edoxaban used as an initial treatment. The patient was a 79-year-old Japanese male with alcoholic cirrhosis. The patient suffered choledocholithiasis and had a mural chronic CA-PVT extending from the superior mesenteric vein to the portal trunk. He underwent open cholecystectomy and choledochotomy. Early postoperative clinical course was uneventful except for abdominal distension due to ascites diagnosed on postoperative day (POD)7 when hospital discharge was planned. Contrast enhancement computed tomography (CE-CT) taken on POD 7 revealed the exacerbation of the CA-PVT. Despite recommendation for extension of hospital admission with low molecular weight heparin treatment, the patient strongly hoped to be discharged. Unwillingly, we selected DOAC, edoxaban, as an initial treatment, which was commenced the day after discharge (POD8). As a result, the remarkable improvement of the exacerbated CA-PVT was confirmed by the CE-CT taken on POD21. Any bleeding complications were not observed. Although a slight residue of the CA-PVT remains, the patient is currently doing well 4 years after surgery and is still receiving edoxaban. Any adverse effects of edoxaban have not been observed for 4 years.. A case of successful treatment of the acute exacerbation of CA-PVT with edoxaban was reported. Moreover, edoxaban has been safely administered in a cirrhotic patient for 4 years. The findings obtained from the present case suggest that DOAC can be used as an initial treatment for CA-PVT even in early postoperative period after major abdominal surgery.

A male patient in his 70s was referred to our department. He was found to have alcoholic liver cirrhosis, esophageal varices, and portal vein thrombosis. Antithrombin III (ATIII) formulation was administered. The thrombus was almost completely lysed 2 days after administration. Because portal vein thrombosis could recur, edoxaban, a direct oral anticoagulant (DOAC), was introduced to prevent recurrence. After 4 months, he showed no recurrence of portal vein thrombosis. In the present case, the combination of an ATIII formulation as initial treatment and edoxaban as maintenance therapy was safe and effective. The combination of ATIII and edoxaban may be a treatment option for patients with portal vein thrombosis.
