巨大张力性肺大疱是肺气肿的一种特殊类型,是由一个或数个肺细叶充气胀破而形成.它往往存在于慢性呼吸道疾患的基础上.由于炎症,一方面使局部小气道不全阻塞或瘢痕组织引起支气管活瓣性阻塞,使肺泡内压不断增加.体积增大.另一方面,使肺泡中弹性蛋白酶与抗蛋白酶失衡,致肺组织损伤.一般性气肿大疤临床上可没有症状,在巨大张力性肺大疱时,临床上可出现压迫症状,如胸闷、气急及呼吸困难等,与自发性气胸很相似,易误诊为气胸.我们报告2例巨大张力性肺大疱均被误诊为气胸.
Giant tonic bullous bulla is a special type of emphysema, is caused by one or several pneumothorax inflation rupture and often it is based on chronic respiratory disease due to inflammation, on the one hand so that the local stingy Road incomplete blockage or scar tissue caused by bronchial valve obstruction, so that the alveolar pressure continued to increase. Volume increases. On the other hand, the alveolar elastase and anti-protease imbalance, resulting in lung tissue injury. General emphysema scar clinical There may be no symptoms, in the huge tension bullous bulge, there may be clinical symptoms of oppression, such as chest tightness, shortness of breath and breathing difficulties, and very similar to spontaneous pneumothorax, easily misdiagnosed as pneumothorax.We report 2 cases of hypertonic lung Large blisters were misdiagnosed as pneumothorax.
