ABSTRACT
Objective To discuss the key technique of ultrasound-guided biopsy in superficial lymph nodes,and to explore the value of ultrasound in qualitative diagnosis for the lymph nodes.Methods Three hundred and twenty-five patients who underwent ultrasound-guided lymph node biopsy from Jan 2006 to Jan 2009 were retrospectively reviewed.Results The sizes of the lymph nodes were 0.8 cm×1.0 cm-5.0 cm×7.0 cm.Each patient was punctured 3 to 6 times.Pathological results showed lymph nodes in 230 patients (70.77%) were malignant,including metastatic carcinoma in 134 patients,malignant lymphoma in 96 patients,while lymph nodes in 87 patients (26.77%) were benign,including specific infection in 82 patients,non-specific infection in 5 patients,whereas uncertain in 8 patients (2.46%) .The tissue amount got from biopsies could be used for qualitative pathological diagnosis in 317 patients (97.54%) .Taking lymph node with the ratio of long diameter to short diameter less than 2,unclear medulla structure,multi-vessel and arterial resistance index≥0.65 as the standard,the diagnostic accuracy rate of malignant lesions was 76.41%.Conclusion Ultrasound-guided biopsy of superficial lymph nodes is convenient and effective for pathological diagnosis.
