supported the use of large gauge(18g) needles since it required few passes, had similar complication rates and equivalent diagnostic yield with that of smaller gauge needle(19.5 and 21g). Apart from the needle size, several other factors have been found to influence the development as well as the severity of post biopsy complications. A study conducted by Wang et al[48] concluded that smoking, supine position and longer needle path within normal lung parenchyma were significant risk factors for post biopsy pneumothorax. Eva Branden et al[8] observed that there was an increased risk for pneumothorax when the biopsied lesion was small or when the emphysema was in the path of the biopsy needle. Stanley et al[49] conducted a study to evaluate the diagnostic yield and complications of CT guided thoracic biopsy. The study associated pneumothorax rate with traversed lung length, lesion size and lesion depth. Risk factors influencing haemoptysis rate were found to be the traversed lung length and lesion size. Analysis of risk factors affecting complications of CT …show more content…

A similar observation was noted by Guimaraes et al[6] in their study that evaluated 362 biopsies. A study conducted by Yeow et al[52] evaluating the risk factors for pneumothorax and bleeding concluded that lesion depth was the most important predictor of post biopsy pneumothorax with the highest incidence reported for subpleural lesions. Radiological evaluation of bronchogenic carcinoma Bronchogenic carcinoma accounts for over 95% of all primary lung tumours[53]. It is the leading cause of cancer deaths in both men and women worldwide accounting for approximately 27% of all cancer deaths[54]. This carcinoma is broadly divided into small cell lung carcinoma (SCLC) and non small cell lung carcinoma (NSCLC). Histologically, NSCLC is sub classified
