目的分析ＣＴ导引下胸部病变穿刺活检的临床应用。材料与方法对４０例胸部病变包括肺内３２例，肺门１例，纵隔２例，胸膜５例患者行ＣＴ定位穿刺活检，采用２０～２１Ｇ抽吸针或９号腰穿针，选最佳层面和进针点，作多点提插旋转穿刺抽吸。结果胸部病变穿刺活检总阳性率：细胞学８４％，组织学１００％，其中２例出现无症状的少量气胸，未发现严重并发症。结论ＣＴ导引下胸部穿刺活检正确率高，并发症少，有利于疾病早期确诊治疗，免除不必要的开放性活检。
Objective To analyze the clinical application of CT guided biopsy of thoracic lesions. Materials and Methods Thirty patients with thoracic lesions including 32 in the lung, 1 in the hilar, 2 in the mediastinum and 5 in the pleura underwent CT-guided biopsy with a 20 to 21 G aspiration needle or a 9-to-16 lumbar needle for the best selection Levels and points into the needle, to mention more points to insert rotary puncture suction. Results The total positive rate of biopsy of chest lesions: cytology 84%, histology 100%, 2 cases of asymptomatic pneumothorax showed no serious complications. Conclusion CT guided chest biopsy with high accuracy, fewer complications, is conducive to the early diagnosis and treatment of diseases, eliminating unnecessary open biopsy.
