The objective in creating an artificial pneumothorax during lung ablation is to develop a working space in the thorax sufficient to displace the target lung lesion from adjacent vulnerable mediastinal or chest wall structures. Attempts to induce a protective pneumothorax with the use of spring-loaded needles were successful in four of six patients, permitting development of safe "windows" for ablation. These pneumothoraces were induced by the introduction of a needle with a spring-loaded, blunt-tipped obturator into the pleural space, followed by injection of room air. Pleural adhesions related to previous interventions may interfere with creation of a pneumothorax. Use of this technique could extend the utility of ablative therapies for lesions adjacent to the mediastinum and chest wall.
在肺部消融过程中制造人工气胸的目的是在胸腔内形成一个工作空间，该空间足以将目标肺部病变与相邻的易损纵隔或胸壁结构分开。使用弹簧针诱导保护性气胸的尝试在6例患者中有4例成功，从而为消融创造了安全的“窗口”。这些气胸是通过将带有弹簧钝头闭孔器的针插入胸膜腔，然后注入室内空气来诱导的。与先前干预相关的胸膜粘连可能会干扰气胸的形成。这项技术的应用可能会扩大消融治疗对纵隔和胸壁附近病变的效用。
