肺病灶针吸活检最常见的并发症是气胸,还可引起肿瘤细胞的种植。为克服这些并发症,本文介绍了一种改良的针吸活检技术,即在CT 引导下应用一个共轴针(Coaxial needle)行针吸活检。30例预行肺病灶共轴针吸活检病人先行胸部CT检查,以确定病灶部位及进针点,同时了解纵隔情况.进针部位常规消毒,1%利多卡因局麻后用16号针对病灶部位垂直刺入,直至针尖接近胸膜。在针管内
Pulmonary lesions needle biopsy is the most common complication of pneumothorax, but also cause the cultivation of tumor cells. To overcome these complications, this paper presents an improved needle aspiration biopsy technique using a coaxial needle needle aspiration biopsy under CT guidance. Thirty patients who underwent preoperative pulmonary needle aspiration biopsy underwent chest CT examination in order to confirm the location of the lesion and the point of the needle as well as the situation of the mediastinum. The needle was routinely disinfected and the 16% Pierce vertically until the tip approaches the pleura. Inside the needle tube
