Abstract:
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.
