[Diagnosis and therapeutic strategies for hepatopulmonary syndrome].

Hepatopulmonary syndrome (HPS) is a common pulmonary complication in patients with liver disease and / or portal hypertension, and is characterized by abnormal arterial oxygenation caused by intrapulmonary vascular dilatation. The pathogenesis of HPS is complex, with a low clinical early diagnosis rate and poor prognosis. HPS currently lacks effective therapeutic drugs; therefore, liver transplantation is the only fundamental treatment. This article summarizes the pathogenesis, clinical manifestations, diagnosis and treatment of HPS in order to further improve the level of clinical screening and diagnosis and treatment of HPS.肝肺综合征（HPS）是肝病和/或门静脉高压患者常见的肺部并发症，其特征表现为肺内血管扩张引起的动脉氧合异常。HPS发病机制复杂，临床上早期诊断率低，预后差。目前HPS尚缺乏有效治疗药物，肝移植是唯一根本治疗手段。现就HPS发病机制、临床表现、诊断及治疗进行概述，旨在进一步提高临床筛查和诊治HPS的水平。.
