Fine Needle Aspiration Biopsy of Mediastinal and Peripheral Pulmonary Masses Guided by Real-time Sonography

摘要: The value of fine needle aspiration biopsy guided by real-time ultrasonography was assessed in 45 patients referred with an intrathoracic mass adjacent to the chest wall. mass, as determined x-ray examination, visualized sonographically and subsequently biopsied 42 patients. Puncture specimen diagnostic 34 (81 percent), including nine 12 (75 percent) previous failure under fluoroscopic guidance. success rate similar pulmonary mediastinal masses, 18 23 16 19 patients, respectively. A obtained 26 31 a malignant mass. No complications were observed except for minimal pneumothorax one patient. Thus, sonographic guidance is safe, easy, reliable method masses wall may also succeed where fluoroscopically has failed.
