[Research progress of hepatic sinusoidal obstruction syndrome].

Hepatic sinusoidal obstruction syndrome (HSOS) is a hepatic vascular disease that begins with injury to hepatic sinusoidal endothelial cells, and has a fatality rate of over 80% in its severe form. Therefore, early diagnosis and treatment are crucial to delay HSOS progression and reduce mortality. However, clinicians' understanding of the disease is still insufficient, and the clinical manifestations of the disease are similar to liver diseases caused by other etiologies, resulting in a high rate of misdiagnosis. This article mainly introduces the HSOS recent developments in the etiology and pathogenesis, clinical manifestations and auxiliary examinations, diagnostic criteria, treatment, and prevention.
