门静脉系统按功能分为脾胃区及门脉肠系膜区。多种原因引起单纯性脾静脉梗阻,致门静脉脾胃区域压力增高超过正常,称左侧门脉高压(left-sided portal hypcrtension,LSPH),又称区域性门脉高压症,或胃区门脉高压症。其病因、病理生理、临床表现、治疗手段和预后与常见的肝硬化性门脉高压症截然不同,为提高临床医生的认识,为此作文献复习。 Portal venous system by function is divided into spleen and stomach mesenteric area portal area. A variety of reasons caused simple splenic vein obstruction, resulting in increased pressure in the portal area spleen and stomach than normal, said left-sided portal hypocrtension (LSPH), also known as regional portal hypertension, or portal hypertension disease.
