Application of Ultrasound Guided Percutaneous Automatic Biopsy of Mediastinal Tumors / 中国医师杂志

ABSTRACT

Objective To assess the value of ultrasound guided percutanuous automatic biopsy of mediastinal tumors.Method Forty-six consecutive biopsies were performed on forty-six patients suffered from mediastinal tumor included 14 thymomas,12 lymphomas,9 metastasis carcinomas,5 mediastinal lung carcinomas,3 teratomas,2 neuroblastomas,1 granulosa cell tumor.Under US guidance,a 18-guage core needle with automatic biopsy device was used.Specimen was fixed with 10% formaldehyde solution.Results The procedure of puncture was successful in all patients.The positive rate histologically was 89%(41/46).No complication (such as hemorrhage,pneumothorax and dyspnoea) was happened.Conclusion We consider that the ultrasound-guided percutaneous needle biopsy is a safe and reliable method for the histological diagnosis of mediastinal tumors.
