Pneumothorax after CT guided transthoracic needle aspiration biopsy of lung masses

The purpose of this study was to analyze the rate of pneumothorax after CT guided transthoracic needle aspiration biopsy [TNAB] of lung masses, using variable needle sizes. A total of 70 patients underwent this procedure, among them, 18 patients [26%] developed pneumothorax with 18G needles 24 patients underwent FNA and seven of them [25%] developed pneumothorax, with 20G needle, 26% developed pneumothorax and with the 22G needle 25% developed Pneumothorax. As a conclusion the study shows that the rate of pneumothorax after CT guided TNAB of lung masses remains almost the same regardless of the size of the needle

effect of size of the needle on the rate of pneumothorax after ct guided transthoracic needle aspiration biopsy of lung masses

Purpose of Study: To analyze the rate of Pneumothorax after CT guided TNAB of lung masses, using multiple needle sizes

Patients and Method: Seventy patients underwent CT guided FNA of the chest masses

Results: Out of seventy, 18 patients i.e.; 26 % developed Pneumothorax. With 18G needle 24 patients underwent FNA and seven of them i.e: 25% developed Pneumothorax. With 20G needle, 26% developed pneumothorax and with the 22G needle 25% developed Pneumothorax

Conclusion: The study shows that the rate of Pneumothorax after CT guided TNAB of Lung Masses remains almost the same regardless of the size of the needle

FNAC and core needle biopsy - A comparison in space occupying lesions of liver

A prospective analysis was conducted on 110 FNAC and results were compared with histologicul reports of patients with intrahepatic focal defects. Cytology permitted a diagnosis of the lesion in 98% cases. When aspirates with insufficient material were excluded [4], the diagnostic accuracy of FNA was 94%. Among the 106 patients who underwent both procedures, FNAC and CNB had the some diagnostic accuracy 94% i.e., sensitivity 96% and specificity 93% of FNAC. There were no complications during the execution of FNAC and CNB. FNAC is an effective and safe method in the diagnosis of focal hepatic lesions, with diagnostic accuracy almost similar to that of CNB. When the two techniques are combined, the accuracy of the diagnosis of malignancy of focal liver lesions increases
