Consider percutaneous transthoracic needle aspiration biopsy when specimens of pulmonary malignancies or infections are needed and bronchoscopy is contraindicated or the lesion is in a peripheral location. Percutaneous needle aspiration biopsy can be performed rapidly, and its diagnostic yield is good to excellent. The chief limitation of this procedure is the high incidence of pneumothorax, which makes the technique unsuitable for ventilated patients. A needle is inserted through the chest wall under fluoroscopic or CT guidance; a small sample is then aspirated through the needle. Operator skill and the use of thin needles help reduce the incidence of complications.
当需要获取肺部恶性肿瘤或感染的标本，而支气管镜检查存在禁忌或病变位于外周部位时，可考虑经皮经胸针吸活检。经皮针吸活检操作迅速，诊断阳性率良好至高。该操作的主要局限性是气胸发生率高，这使得该技术不适用于机械通气患者。在荧光透视或CT引导下，将针穿过胸壁插入；然后通过针吸取少量样本。术者的操作技巧以及使用细针有助于降低并发症的发生率。
