Bronchiectasis can result in hemoptysis and, in severe lesions, death by shock and asphyxia. The treatment is: surgery is an option for limited lesions, and for diffuse extensive lesions, only conservative treatment is available. In the case of diffuse widespread lesions, only conservative treatment is possible. A CT chest examination is required to determine the nature of the lesion. If surgery is performed, the timing of surgery is better before the age of 50, the risk is slightly lower, to older age 60 years or more, the risk of surgery is large. Indications for surgery are: patients with recurrent severe acute respiratory infections or massive hemoptysis, lesions generally not exceeding two lung lobes, age generally between 10 and 50 years, good general condition, and no serious impairment of cardiopulmonary function. According to postoperative follow-up, surgical removal of the lobes is curable in limited lesions, and patients with massive hemoptysis sometimes require emergency surgical treatment. Patients with extensive lesions or with severe emphysema and severely impaired pulmonary function are contraindicated for surgery.
