CT引导下经皮肺穿刺活检的临床应用(附117例分析)

目的 探讨CT引导下经皮肺穿刺活检的临床应用价值。方法 对117例肺部病变（肿块66例，结节42例，实变9例）行CT引导下经皮肺穿刺活检。采用18G穿刺针，选择最佳层面进针点多点取材，活检后行组织学和细胞学检查。结果 穿刺的成功率为94．1％。117例中，肺癌84例，其中穿刺确诊77例，穿刺敏感性为91．7％，特异性为82．5％，假阴性7例，假阴性率为17．5％，无假阳性。良性病变33例，经手术和随访证实。共7例发生气胸，占14．5％，仅2例经插管处理。结论 CT引导下经皮肺穿刺准确性高，并发症少，安全可靠，可为临床提供诊断依据，值得推广。

Clinical application of CT- guided fine - needle percutaneous biopsy in the diagnosis of lung lesions (An analysis of 117 cases)

Objective To evaluate the value of CT - guided fine - needle percutaneous biopsy in patient with lung lesions. Methods CT - guided fine - needle percutaneous biopsy were performed in 117 patients with lung lesions, included 66 masses, 42 nodules, 9 lung consolidations. 18 G needles had been used to biopsy from the best - chosen level and situs. Cytologic and histologic studies were done after biopsy. Result The successful puncture rate were 94.1% .Of 117 cases studied,84 were proved to be cancers.77cases were confirmed by biopsy.The sensitivity of biopsy was 91.7% and specificity of biopsy was 82.5 % . Teases were false negative . No false positive was found. 33 cases were benign lesions, confirmed by pathology and clinical course. 7cases occured pneumthrax (14.5 % ), 2 of them need chest tube drainge. Conclusion CT - guided fine - needle percutaneous biopsy is a successful efficient and safty diagnostic method with high accuracy and few complications. It can provide evidence for clinical diagnosis and it is suggested to be used more widely .
