肺萎陷与气胸鉴别方法初探

The primary investigation of methods to distinguish pulmonary collapse from pneumothorax

目的探讨鉴别肺萎陷与气胸的方法。方法5名肺癌患者,其中合并气胸3例,合并右胸腔积液1例,合并以积液为主右液气胸1例。合并胸腔积液患者先行闭式胸腔引流术加负压抽完胸液后,影像学检查尚见气胸,进行闭式胸腔引流抽气却未见气体抽出,合并气胸者进行闭式胸腔引流抽气亦未见气体抽出。所有患者在CT引导下,将含有10ml气体的注射器穿刺进入胸腔,见气体吸入胸腔。结果考虑5例患者存在肺萎陷。结论肺萎陷与气胸的鉴别方法:胸部影像学示气胸,行闭式胸腔引流术抽气未见气体抽出,可在CT引导下将含有10ml气体的注射器穿刺进入胸腔,见气体吸入胸腔者,考虑存在肺萎陷。

Objective To distinguish pulmonary collapse from pneumothorax. Methods Of 5 lung cancer patients 3 cases complicated with pneumothorax, 1 case with right pleural effusion, and 1 case with hydropneumothorax. Patients with pleural effusion after treatment of closed thoracic drainage, chest radiograph showed pneumothorax;Patients with pneumothorax after treatment of drainage pleural had not extract air; guiding by CT scan, 10ml air was injected to the chest, the air was sucking in the chest, that would involve pulmonary collapse. Results 5 lung cancer patients were pulmonary collapse. Conelusion Method to distinguish pulmonary collapse from pneumothorax is chest radiograph and CT scan showed pneumothorax, after treatment of closed thoracic drainage, there is no air to be extraced, then guide by CT scan,inject 10ml air into the chest if the air is sucked in the chest ,which would implicata pulmonary collapse.
