Clinical value of ultrasound-guided percutaneous biopsy in peripheral pulmonary masses

Objective To explore the clinical value and notices needed in using ultrasound-guided percutaneous puncture biopsy for peripheral pulmonary lesions.Methods 33 patients suspicious of peripheral pulmonary lesions with CT and/or X-ray underwent Biopsy-gun percutaneous biopsy under the guidance of ultrasound.The specimens were sent for histopathological examination.Statistical analysis of pathological findings and complications was conducted.Results The 33 cases all secured qualified specimens.The puncture success rate was 100%.31 of the 33 cases were identified and another 2 cases were diagnosed after excision of pathologic findings.Among the diagnosed,malignant lesions were found in 26 cases,benign lesions in 7 cases,complications in 2 cases.One case was found to have sputum with blood and another case induced angina.Conclusion Ultrasound-guided percutaneous lung biopsy is a safe,convenient and minimally invasive method.It should be recommended as the first choice for the detection of pulmonary peripheral lesions.
