CT引导经皮胸腔穿刺活检术33例临床分析

Chest biopsy by CT-guided percutaneous fine needle punctures:Report of 33 cases

目的:探讨CT引导经皮胸部穿刺活检对胸部占位性病变的诊断价值。方法:联合应用17G、18G软组织切割式活检针和21G抽吸针、PTC针对胸部占位33例在CT引导下穿刺活检。结果:33例经皮胸腔穿刺活检患者中,结合临床资料及病理检查证实为原发性肺癌25例,结核1例,胸腺癌1例,转移性癌2例,未能作出明确诊断者4例;诊断准确率为87.9%,术后并发气胸1例,痰中带血3例。结论:CT引导经皮胸腔穿刺活检是一种比较安全、可靠的辅助诊断技术,值得临床推广应用。

Objective：To explore the clinical value of chest biopsy by CT-guided percutaneous fine needle punctures in diagnosis of space-occupying lesions of the chest.Methods：Thirty-three cases of the chest lesion were performed biopsy by combined use of 17G and 18G soft-tissue-cutting biopsy needles,21G fine-needle and PTC needle with the guide of CT.Results：Among the 33 cases,25 were confirmed by clinical data and pathological examination to suffer from primary malignan tumor,1 from tuberculosis,1 from thymus cancer and 2 from metastatic carcinoma.Indefinite diagnosis was made in 4 cases.The diagnosis rate was 87.9%.After operation,pneumothorax occurred in 1 case and traces of blood in sputum were found in 3 cases.Conclusions：Chest biopsy by CT-guided percutaneous fine needle punctures is a safe and practical technique and may be widely used in clinical application.
