Pulmonary alveolus resection is generally a localized resection of lung tissues, and there will be some sequelae after the operation, mainly including respiratory limitation, chest pain, and thoracic collapse. 1. Respiratory limitation: postoperative pleural adhesions may occur, affecting the expansion of the chest cavity, further leading to respiratory limitation and causing a series of symptoms such as wheezing. 2. Chest pain: Post-operation may cause localized irritation of the pleura, which may lead to localized pulling during exercise, resulting in painful and uncomfortable symptoms. 3. Thoracic collapse: if too much lung tissue is removed, the corresponding thoracic condition may be affected, resulting in local thoracic collapse, but this is rare. If there is obvious shortness of breath, dyspnea, chest pain, etc. after alveolar resection, it is necessary to consult a doctor in time for observation, and after diagnosing the cause of the disease, carry out standardized treatment under the guidance of the clinician, so as to avoid delaying the condition.
