作者等对19例纵隔病变作了细针吸取细胞学检查。应用这种方法,能在术前得到有价值的资料,有助于内、外科医师的诊治,同时对少数病人可避免不必要的手术。具体方法:选择纵隔病变(不包括明显的支气管肿块直接扩展至纵隔者),局麻后,在电视荧光监视下作针吸,使用22或23号细针及19号套管,经胸壁进入 The authors made fine needle aspiration cytology for 19 cases of mediastinal lesions. Using this method, valuable information can be obtained before surgery to help internal and external surgeons, and at the same time avoid unnecessary surgery for a small number of patients. Specific methods: Select mediastinal lesions (not including obvious bronchial masses that directly extend to the mediastinum). After local anesthesia, perform needle aspiration under television fluorescence monitoring. Use 22- or 23-gauge needles and 19-gauge cannula to enter the chest wall.
