Objective: To evaluate the successful and complications of transthoracic needle aspiration (TTNA) of thoracic mass under CT scan guidance in BMA Medical college and Vajira Hospital.

Study design: Descriptive study.

Subjects: One hundred patients with thoracic mass underwent transthoracic needle aspiration (TTNA) at Diagnostic Radiology Division, Department of Radiology during January 2000 to June 2006 were enrolled.

Methods: Demographic data, clinical data and cytological reports from medical records were retrospectively reviewed and analyzed.

Main outcome measures: Successful rate, complications.

Results: From 100 patients, 93 patients presented with lung mass and 7 patients with mediastinal mass. Satisfactory specimen for conclusive cytological diagnosis and unsatisfactory specimen (inadequate) were 94% and 6%. For satisfactory specimens, 56% were diagnosed malignant neoplasm and 38% were benign lesion. The complication occured in 3 patients. Two patients had minimal pneumothorax detected by CT scan and 1 patient had transient minimal hemoptysis. These three patients did not require further treatment after observation.

Conclusions: The successful of TTNA of thoracic mass lesion under CT scan in BMA Medical College and Vajira Hospital was high and complication rate was acceptable.
