CT导向经皮肺穿刺活检的临床应用

目的 探讨CT导向经皮肺穿刺活检用于肺占位性疾病诊断的意义。方法 采用DLTRA－CUT型16G、18G、20G软组织切割式活检针在PICKER IQ CT机导向下穿刺诊断35例肺占位性疾病。结果 35例经皮肺穿刺活检，经病理检查证实26例为原发性恶性肿瘤，1例转移性癌，3例结核，3例炎性假瘤，2例未能明确诊断，诊断率为94．3％。术后5例出现少量气胸，2例出现血丝痰，均未做特殊处理。结论 CT导向经皮肺穿刺活检是比较安全、实用的技术、可以在有条件的单位广泛应用。

Clinical application of lung biopsy through CT-guided percutaneous paracentesis

Objective To explore the significance of lung biopsy through CT guided percutaneous paracentesis in the diagnosis of space occupying lesions of the lung. Methods Thirty five patients with space occupying lesions of the lung underwent lung biopsy through CT guided percutaneous paracentesis and DLTRA CUT 16G, 18G or 20G soft tissue cutting biopsy needles and PICKER IQ computerized tomograph were used. Results Of the 35 patients, 26 were confirmed by pathological examination to suffer from primary malignant tumor, 1 from metastatic carcinoma, 3 from tuberculosis and 3 from inflammatory pseudotumor. No definite diagnosis was made in two patients. The diagnostic rate was 94.3%. After operation, minor pneumothorax occurred in 5 cases and traces of blood in sputum in 2 cases, however, they didn't need any treatment. Conclusion Lung biopsy through CT guided percutaneous paracentesis is a safe and practical technique and may be widely used in hospitals if conditions permit.
