Analysis of ultrasound guided percutaneous lung biopsy and ultrasound image / 实用医学杂志

ABSTRACT

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.
