What is the cause of pulmonary bullae around 30 years old?

Pulmonary bullae are more common in young people, because their bodies grow too fast and their lungs develop slowly during puberty, so they are more common in slender men, and pulmonary bullae are generally located at the apex of the lungs.

The first spontaneous pneumothorax can generally be treated conservatively, and the recurrence rate is 50%.

Spontaneous pneumothorax occurring for the second time and above is very likely to recur, so don't hesitate. It should be treated with injury and healed well. Thoracoscopic surgery is selected for the operation, and 2-3 small incisions 1-2cm are made in the chest cavity, which has the advantages of less trauma, quick recovery and good healing, but the cost is slightly higher. If economy is considered, subaxillary small incision thoracotomy is feasible, and the recovery is the same.
