Patient: right pulmonary vascular malformation with limited dysplasia. The doctor recommended an elective hospitalization for interventional embolization. Now I have no obvious symptoms and occasionally have a dry cough.1. Do I need surgical treatment in this case? What is the risk of surgery? 2.The left lung had no lesion two years ago, but now it is said to be an old lesion, is it related to the right lung? 3.If I don’t have surgery, how often should I have a CT review and what should I pay attention to in my normal life? Wang Xiaohang, Department of Thoracic Surgery, Shandong Provincial Hospital: Can we do angiography to see if it is suitable for interventional treatment? Surgical resection is possible, but surgery may mainly involve the risk of haemorrhage. The inflammation of the left lung may be related to the repeated infection spread caused by the developmental malformation of the lower lobe of the right lung. If you do not have surgery, you should avoid colds, strenuous activities, colds, and trips to plateaus and remote areas, etc.
