We performed 52 percutaneous lung biopsies on 34 animals (NZ rabbits) using a coaxial needle system. In 19 animals we introduced homologous clotted blood through the outer plastic cannula in order to prevent a pneumothorax. CT was used to demonstrate the pneumothorax. The aim of the experiment was to see whether clotted blood would reduce the incidence of pneumothoraces. In addition we wanted to determine the complications of this method. We found that, correctly used, clotted blood significantly reduced the incidence of pneumothoraces (31.57% as against 64.70% in the control group). It also reduced the extent of the pneumothorax. The method has no complications.
我们使用同轴针系统对34只动物（新西兰兔）进行了52次经皮肺活检。在19只动物中，我们通过外部塑料套管注入同源凝血以预防气胸。使用CT来显示气胸。该实验的目的是观察凝血是否会降低气胸的发生率。此外，我们还想确定该方法的并发症。我们发现，正确使用时，凝血可显著降低气胸的发生率（31.57%，而对照组为64.70%）。它还减少了气胸的程度。该方法无并发症。
