目的探讨CT引导经皮肺穿刺活检对肺内病灶的诊断价值。方法应用美国COOK公司18-22G负压穿刺切割式活检针,在CT引导下对52例肺占位性疾病患者进行经皮肺穿刺活检。结果52例肺穿刺活检患者中,病理检查证实为原发性肺癌者31例,结核5例,炎性假瘤14例,未能作出明确诊断者2例,诊断准确率为96.1%,术后并发少量气胸4例(7.7%),痰中带血5例(9.6%),均未作特殊处理。结论CT引导经皮肺穿刺活检为一种安全、可靠的辅助诊断技术。
Objective To investigate the value of CT guided percutaneous lung biopsy in the diagnosis of intrapulmonary lesions. METHODS: Fifty-two patients with lung-space-occupying disease underwent percutaneous pulmonary biopsy under the guidance of CT with the 18-22G negative pressure biopsy needle from COOK Corporation of the United States. Results Of the 52 cases of lung biopsy, 31 cases were confirmed as primary lung cancer by pathological examination, 5 cases were tuberculosis and 14 cases were inflammatory pseudotumor. Two cases failed to make a definite diagnosis, and the diagnostic accuracy was 96.1% Concurrent with a small amount of pneumothorax in 4 cases (7.7%), bloody sputum in 5 cases (9.6%), no special treatment. Conclusion CT guided percutaneous pulmonary biopsy is a safe and reliable auxiliary diagnosis.
