Pulmonary bullae

Pulmonary bulla refers to the air sac containing cavity formed in the lung tissue due to the increase of pressure in the alveolar cavity, the rupture of alveolar wall and mutual fusion due to various reasons. Pulmonary bullae are congenital and acquired. Congenital is more common in children. It is caused by congenital bronchial dysplasia, valvular mucosal folds and poor cartilage development, resulting in the function of valve. Acquired is more common in adults and elderly patients, often accompanied by chronic bronchitis and emphysema. At present, the vast majority of pulmonary bullae surgery can be completed under video-assisted thoracoscopy, and the postoperative symptoms of 2 / 3 patients are significantly improved.
