CT导引胸部穿刺活检

目的：评估ＣＴ导引经胸壁穿刺活检的方法学和临床价值。材料和方法：１９９４年２月至１９９７年１０月对５５例患者进行了ＣＴ经胸壁穿刺活检，其中肺内病变４３例，胸膜病变５例，纵隔病变６例，肺和胸膜同时病变１例；２５例行细胞学和病理组织学检查，余３０蚝病理组织检查。结果：所有５５例患者ＣＴ导引下均穿刺到位，并获得细胞学和组织学材料；细胞学检查符合率６０％，病理组织学检查符合率８７．５％，其中３５例肿瘤患者

Preliminary Study of CT-guided Transthoracic Puncture Biopsy.

Purpose:Evaluation of technique and clinical value of CT-guided transthoracic punc ture biopsy.Materials and methods:Between Feb 1994 and Oct 1997,CT guided transthoracic puncture biopsy was performed in 55cases including unknown pulmonary(44cases),pleural(6 cades)and mediastinal (6 cases)diseases with 20gDFBN and 18g ADGSTN.36 males and 19 females,aged from 23 to 78 years (mean age 55 years)were included.The assembled materials were evaluated cytologically in 25 cases and histopathologically in 55 cases.Results:The needle tip passed through percutaneouslly into the lesion under CT-guided in all 55 cases and obtained specimens for cytology(25 cases)and histopathology(55 cases).Accuracy rate were 60% for cytology and 87.5% for histopathology.Among 35 cases of tumor, histopathologic classification had been done in 26 cases.Complication occurred in 7cases(13%),including pneumothorax(2 cases)and hemoptysis(5 cases).Conclusion:CT-guided TPB is a method of combining advanced imaging tecnique and pathology.It is a simple,highly accurate,safe diagnostic tool,especially for unknown pulmonary,pleura,mediastinal lesions.
