Patient: In 91 years, there was blood in the sputum several times, and then it was relieved, love cold, after cold sputum but no blood, in 06 years back pain CT showed branched dilatation, left lung lower lobe heavy, right lung lower lobe light, for two years every day regular discharge of pus sputum, pain is unusual, when heavy infusion or Chinese medicine treatment. 09 years sputum became white, less until now Is it possible to operate? Hospital thoracic surgery: If the lung function is normal and can withstand a total pneumonectomy on one side, then we can consider a staged operation, first removing the side with heavy symptoms (usually the side with the heavier lesion on CT), and if the symptoms improve significantly, then we can temporarily not remove the branched lesion with light symptoms. If the lung function can only tolerate one lower lobe resection, the surgery should be cautious and the source of symptoms should be clarified before considering whether to operate.
