FNAC is the simplest method to get tissue . Localization for TTFNAC is the main hindrance for this method of diagnosis especially in developing counties. US guided FNAC may be opted in poor resource countries if adequate evidence are obtained in favour of it.Aim of Study: To determine the diagnostic yield and safty of US guided FNAC in diagnosis of intrathoracic lesions.Materials & Methods: All patients admitted with radiological lesion strongly suggestive of pulmonary malignancy were selected for FNAC. Ultrasonography were done to assess the location, size and echogenicity of the lesion. The depth of lesion from skin surface is assessed and site of puncture is marked. FNAC is done using No. 23 G lumber puncture needle in presence of sonologystResults: A total of 22 cases were studied. All were males and were smokers. Age distribution was from 28 years to 67 years with a peak incidence between 61 to 70 years. 50% (11) had lesions in right and mid zone, followed by left mid zone (35% [8], size of radiological lesion varied from 3-7 cms, with two third in 5-7 cms group. There was considerable number (6) of smaller lesions (3-4 cms) also. Ultrasound location was possible in 21 cases. Four cases required a second TTAB for a definite option of which 3 turned out to begin lesions. Overall yield was 91%.Only two patients developed complications (9%). One had mild heamoptysis and the other minimal pneumothorax.Conclusions: Ultrasound guided TTAB is safe, accurate, quick and economical.with very low incidence of complications.
