Wang X and Wang YG

Hepatic sinuses obstruction syndrome (HSOS) also known as hepatic venule syndrome, refers to the injury of central lobe and sub-lobular vein of hepatic lobule, resulting in intrahepatic posterior sinus portal hypertension caused by lumen stenosis or occlusion. Currently the pathogenesis is not clear. It may be related to the drug, immunity and inflammation of the liver vein endothelial cells. The clinical manifestations are hepatomegaly, right upper abdominal pain, jaundice and ascites, with a high risk of mortality and poor prognosis for characteristics. Occurs because of cytoreductive therapy prior to hematopoietic stem cell transplantation (HSCT), adjuvant or neoadjuvant chemotherapy containing oxaliplatin for colorectal carcinoma metastatic to the liver and treated by partial hepatectomy, taking herbal remedies containing pyrrolizidine alkaloid and the autosomal recessive condition of veno-occlusive disease with immunodeficiency (VODI). In this paper, the clinical characteristics of HSOS caused by sedum uizoon were analyzed in detail, which provided clinical data for the diagnosis and treatment and the mechanism of the disease in the future.
