CT引导下经皮穿刺肺内小结节病变的应用价值

Application value of CT-guided percutaneous transthoracic needle biopsy of small pulmonary nodules

目的探讨CT引导下经皮穿刺肺内小结节病变的应用价值。方法经细胞学、组织学或临床随访证实的病例39例,病灶直径为1.0～3.0cm(平均直径2.1cm)。穿刺后即刻至7d内行CT复查及临床观察,看有无并发症的发生。病例随访时间为3～28个月,平均13个月。结果39例中,经手术后病理检查或临床随访确诊为恶性肿瘤者21例,其中,穿刺与手术或临床随访结果一致者17例;经手术后病理检查或临床随访确诊为良性病变18例,其中穿刺与手术或临床随访结果一致者14例。恶性肿瘤的准确性为81%(17/21),良性病变的准确性为73%(14/18)。发生并发症者8例(20%),其中气胸6例(15%),咯血2例(5%)。结论CT引导下经皮穿刺活检对肺内小结节病变的定性有重要价值。

[Objective] To investigate the application value of CT-guided percutaneous transthoracic needle biopsy of small pulmonary nodules. [Methods] 39 cases proved by cytopathologic and histopathologic examination or clinic follow-up information were collected. The nodule diameters were 1.0～3.0 cm （mean 2.1 cm）. Each case was reviewed for complications after the operations in 7 days. The majority of the people were observed in 3～28 months （mean 13 months）. [Results] Of 39 cases studied, 21 cases were proved to be malignant and 18 cases were benign lesion. The malignant diagnostic accuracy was 81% （17/21） and the benign 73% （14/18）. 6 cases occurred pneumothorax and emptysis were seen in 2 cases. [Condusion] CT-gnided percutaneous transthoracic needle biopsy is very important to confirm the character of the small pulmonary nodules.
