From 1983 to 1993, we performed ultrasonically guided percutaneous needle biopsies on 320 thoracic tumors. Of these, 77 tumors were smaller than 3 cm in diameter and were peripherally located adjacent to the chest wall (n = 71) or in the posterior mediastinum (n = 6). We evaluated the efficacy and safety of UGNB for diagnosing these small lesions. The mean tumor size was 2.0 +/- 0.7 cm. Nine nodules were less than 1.0 cm in diameter, 38 were between 1.1 and 2.0 cm, and 30 were between 2.1 and 3.0 cm. Biopsies were done with a 17-gauge Trucut needle; a 21-gauge needle was used to aspirate specimens for cytological study. A definitive diagnosis was made in 31 (77%) of 40 malignant lesions and in 19 (51%) of 37 benign lesions. Complications included pneumothorax (n = 5) and hemoptysis (n = 3), but no special medications were needed. Thus, real-time sonographic guidance is a safe, easy, and reliable biopsy method for small pulmonary and mediastinal nodules adjacent to the chest wall.
1983年至1993年期间，我们对320例胸部肿瘤患者进行了超声引导下经皮穿刺活检。其中，77个肿瘤直径小于3 cm，位于周边，紧邻胸壁（n = 71）或后纵隔（n = 6）。我们评估了超声引导下经皮穿刺活检（UGNB）诊断这些小病变的有效性和安全性。肿瘤平均大小为2.0 +/- 0.7 cm。9个结节直径小于1.0 cm，38个在1.1至2.0 cm之间，30个在2.1至3.0 cm之间。活检采用17号Trucut针；用21号针抽吸标本进行细胞学研究。40例恶性病变中有31例（77%）、37例良性病变中有19例（51%）获得了明确诊断。并发症包括气胸（n = 5）和咯血（n = 3），但无需特殊药物治疗。因此，实时超声引导是一种安全、简便且可靠的活检方法，适用于紧邻胸壁的小肺结节和纵隔结节。
