X线显示右侧气胸、心影左移


X线显示右侧气胸,可见心影左移。气胸发生于穿透性的胸部损伤、肺气肿肺大疱破裂、正压通气。空气进入胸膜腔挤压肺组织。图为张力性气胸,因呼吸时活瓣样的结构使气体漏入到胸膜腔的越来越多,纵膈移位。闭式引流管可排出胸膜腔内的气体使萎缩肺膨胀。
This radiograph demonstrates a right pneumothorax. Note the displacement of the heart to the left. A pneumothorax occurs with a penetrating chest injury, inflammation with rupture of a bronchus to the pleura, rupture of an emphysematous bulla, or positive pressure ventilation. The escape of air into the pleural space collapses the lung. The example seen here is a "tension" pneumothorax shifting the mediastinum, because a "ball-valve" air leak is increasing the air in the right chest cavity. A chest tube can be placed to re-expand the lung.
