摘要：
Objective Analysis of ultrasound guided percutaneous lung biopsy and ultrasound examina-tion results,to explore the application value of ultrasound in the diagnosis of benign and malignant lung mass. Methods Application of percutaneous biopsy guided by ultrasound in 109 cases by X-ray and CT examination revealed lung mass patients,analysis of biopsy results and ultrasonographic characteristics,biopsy success rate and complication also be observed. Results The experimental group of 109 cases comprised 98 cases of peripheral mass and 9 cases of central mass with pulmonary consolidation ,81 cases of malignant lesions(74.3％),26 cases benign lesions(23.9％),2 cases were falied(1.8％). 107 cases were success at first operation ,and 5 cases had hemoptysis( incidence 3.8％). The echo types of malignant lesions and benign lesions had significant difference(χ2=2.422,P<0.05),but both of them had intersecting. Malignant lesions were larger than benign lesions(t=1.58, P < 0.05),but the size of malignant lesions with benign lesions had intersecting. Patients with malignant lesions had more or abundant flow,patients with benign lesions had none or fewer flow(χ2=8.471,P<0.05). but they also had intersecting. Conclusions Ultrasonography of benign and malignant lesions in peripheral pulmonary mass and central type with consolidation has certain characteristics. Ultrasound guided percutaneous lung biopsy has major value in determining the pathological type of lung mass and it is safe ,reliable and easy to process.%目的 分析肺肿块超声引导经皮肺肿块穿刺活检结果及超声声像图特点,探讨超声引导穿刺活检以及超声检查在肺肿块良恶性诊断中的应用价值.方法 对109例经X线及CT检查发现的周围型肺部肿块及中央型肿块伴肺实变患者应用超声引导经皮穿刺活检,分析患者穿刺活检病理结果、穿刺活检成功率,穿刺并发症以及超声声像图特征.结果 109例穿刺活检者,周围型肿块98例,中央型肿块伴肺实变9例,其中恶性病变81例(74.3％),良性病变26例(23.9％),2例不能成功取材(1.8％),余107例患者均一次取材成功(98.2％).109例穿刺患者中,5例出现咯血(4.5％),其他无不适.超声声像图表现:良性病变多边界清楚、回声均匀,恶性病变多边界不清、回声不均匀(χ2=2.422,P<0.05),但二者有一定交叉;恶性肿块较良性肿块大(t=1.58,P<0.05),但良恶性病变径线比较有一定交叉;恶性病变血流多较丰富而良性病变多为少血供或无血供(χ2=8.471,P<0.05),但二者也有一定交叉.结论 超声引导经皮肺肿块穿刺活检安全可靠,简便易行,对确定病理分型具有重要意义.超声声像图在肺周围型肿块及伴实变中央型肿块的良、恶性鉴别中具有一定特征性.
