To study the profitability and complications of the puncture aspiration with thoracic thin-needle (PATTN).
The results of 160 PATTN, performed under TC control in 131 men and 29 women, average age 61.24 +/- 15.17 years were analyzed. The diagnosis obtained by PATTN was compared with the definitive diagnosis made with biopsy (bronchial, thoracotomy, or mediastinoscopy), the evolution or response to treatment, or at autopsy. Factor related to greater diagnostic reliability and risk of pneumothorax were analyzed.
For the diagnosis of non-tumoral pathology, the technique achieved a sensitivity (S) of 90 percent, specificity (E) of 96.06 percent, and reliability (F) of 91.71 percent, while in malignant processes, S 72.4 percent, E 100 percent and F 88.52 percent, with a histological correlation of 72.72 percent in the first case and 68.80 percent in the second. The localization in superior lobes, radiological pattern of multiple or cavitied nodules, and size > 2 cm were identified as factors which significantly increased reliability. Pneumothorax was produced in 24 cases (15 percent) and was more common in patients diagnosed of COPD, with a lesion < 2.1 cm, and not attached to the pleura.
The PATTN offers considerable profitability for the diagnosis of thoracic lesions of any localization and nature, at low costs and with few serious complications.
研究胸部细针穿刺抽吸术（PATTN）的收益及并发症。
分析了160例在CT引导下进行的PATTN结果，其中男性131例，女性29例，平均年龄61.24±15.17岁。将PATTN获得的诊断结果与通过活检（支气管镜检查、开胸手术或纵隔镜检查）、病情演变或治疗反应或尸检做出的最终诊断进行比较。分析与更高诊断可靠性及气胸风险相关的因素。
对于非肿瘤性病变的诊断，该技术的敏感性（S）为90%，特异性（E）为96.06%，可靠性（F）为91.71%；而在恶性病变中，S为72.4%，E为100%，F为88.52%，第一种情况的组织学相关性为72.72%，第二种情况为68.80%。上叶定位、多个或空洞结节的放射学模式以及直径大于²cm被确定为显著提高可靠性的因素。24例（15%）发生了气胸，在诊断为慢性阻塞性肺疾病（COPD）、病变小于2.1cm且未附着于胸膜的患者中更常见。
PATTN对于诊断任何部位和性质的胸部病变具有可观的收益，成本低且严重并发症少。
