Low-molecular-weight heparin followed by rivaroxaban for acute occlusive portomesenteric vein thrombosis in a cirrhotic patient treated with multiple endoscopic variceal procedures.

Acute portomesenteric vein thrombosis is potentially lethal. In the present paper, a cirrhotic patient with a previous history of esophageal variceal bleeding presented with acute occlusive portomesenteric vein thrombosis, but achieved complete recanalization by low-molecular-weight heparin followed by rivaroxaban. Notably, no bleeding episode occurred during anticoagulation therapy. This case supported early initiation of anticoagulation in such patients.
