超声引导经皮肺肿块穿刺活检在临床诊断中的应用

Clinical Application of Percutaneous Pulmonary Tumor Puncture Biopsy Guided by Ultrasound

应用超声引导经皮自动穿刺活检术对79例经X线及CT检查发现肺部肿块患者进行穿刺活检,分析患者穿刺活检二维声像图特征,彩色血流信息特征,病灶内造影剂增强情况,穿刺活检成功率及并发症情况,探讨超声引导经皮肺肿块穿刺活检在肺肿块病变临床诊断中的应用价值。结果发现:实验组79例患者中,周围型肿块73例,中央型肿块伴肺实变6例,恶性病变60例,良性病变19例。恶性病变病灶回声类型、病灶最大径线、Adler血量分级、病灶内造影剂均匀性与良性病变同类指标比较具有显著差异性(p<0.05)。可见:超声引导经皮肺肿块穿刺活检是安全可靠,简便易行的方法,其良、恶性病变二维声像图特征,彩色血流信息特征,病灶内造影剂增强情况差异显著,在肺周围型肿块及伴实变中央型肿块患者的病理分型诊断中具有重要的应用价值。

Percutaneous automatic biopsy guided by ultrasound was applied in 79 cases of patients with lung tumor, who were diagnosed by X-ray and CT examination. Two-dimensional ultrasonographic characteristics, color flow information, the contrast agent enhancement of focus, biopsy success rate and complications were analyzed to explore clinical application value ofpercutaneous lung tumor puncture biopsy guided by ultrasound in the diagnosis of lung mass lesion. Results from the study found that among the 79 patients, there were 73 cases of peripheral mass, 6 cases of central mass with pulmonary consolidation, 60 cases of malignant change, and 19 cases benign lesions. The comparison of echo types in malignant lesions, the maximum diameter line, lesions Adler HP grading, contrast agent uniformity with those of benign lesions was significantly different （p 〈0.05）. Consequently, percutaneous lung tumor puncture biopsy guided by ultrasound was safe, reliable and simple. Two-dimensional ultrasonographic characteristics, color flow information characteristics and enhancement of contrast agent of the benign and malignant lesions were significantly different. This study provided important application value in diagnosis of patients with pulmonary peripheral mass and central mass.
