目前微创技术在医学界各学科受到广泛重视,应用单腔静脉导管进行胸腔闭式引流术治疗中等及大量结核性胸腔积液也逐渐被有识之士认同。因该项操作技术需要一定的操作技巧和较全面的专科知识及超声影像方面的知识,如不了解单腔静脉导管进行胸腔闭式引流术的适应证及技术要点,往往达不到理想的治疗效果。笔者应用单腔静脉导管进行胸腔闭式引流术治疗中等及大量结核性胸腔积液40例,治疗效果良好。其操作简便快捷,效果确切,现介绍如下,以供广 Currently, minimally invasive techniques are widely used in all disciplines in the medical field. The use of single vena cava catheters for the treatment of moderate and large amounts of tuberculous pleural effusion has also been accepted by people of insight. Because of the operating skills require a certain degree of operating skills and more comprehensive expertise and knowledge of ultrasound imaging, such as do not understand the single vena cava for indications and technical points of closed thoracic drainage, often fail to achieve the desired treatment effect. The author of single vena cava catheterization of thoracic drainage for the treatment of moderate and large amounts of tuberculous pleural effusion in 40 cases, the treatment effect is good. The operation is simple and quick, the exact effect, are presented below, for the wide
