静脉系统梗阻-高压性疾病(VOH)是一类严重危害人类健康的常见病,发病率逐年上升。我国是VOH的高发国家。但长期以来,在VOH的临床治疗上一直缺少安全有效的方法。近年来,随着介入放射学的发展,微创性介入技术已逐步成为VOH临床治疗的首选方法。但在本研究立项之前,因技术能力和器材条件及经济状况所 Venous System Obstruction - High Pressure Disorder (VOH) is a common form of disease that is a serious human health hazard and its incidence is increasing year by year. Our country is a high incidence of VOH countries. However, for a long time, there is a lack of safe and effective methods for the clinical treatment of VOH. In recent years, with the development of interventional radiology, minimally invasive interventional techniques have gradually become the preferred method of clinical treatment of VOH. However, prior to the research project, due to technical capabilities and equipment conditions and economic conditions
