Abstract :

Background : Transthoracic CT guided needle biopsy of an indeterminate pulmonary mass/ nodule is a well established, highly accurate and minimally invasive diagnostic procedure. Lesion characteristics have no significant impact on diagnostic yield. Sensitivity and specificity for detection of malignancy are high for CT guided lung biopsy. Even the positive and negative predictive values are high. The diagnostic accuracy is also quite high with this procedure .So purpose of the study is to assess type of complications and factors affecting complications in patients undergoing CT guided lung biopsy. Methodology : A total of 224 patients with lung lesions who had undergone a CT guided lung biopsy using a core biopsy needle were studied to know the various complications, their rate of occurrence and accuracy over a period of two years. Result : 25.0% of the cases who belongs to < 20 years of age had haemorrhage complication followed by 20.0% of the cases that belongs to 20 – 40 years of age and 15.4% who belongs to > 40 years of age had haemorrhage complication.

25.0% of the cases who belongs to < 20 years of age had pneumothorax complication. 12.0% of the cases that belongs to 20 – 40 years of age and 13.3% who belongs to > 40 years of age had pneumothorax complication. Conclusion: The technical and diagnostic accuracy is high with this technique. Thus it can be concluded that CT guided biopsy using a semi-automated core biopsy needle for lung is a highly accurate and safe procedure for lung lesions.
