Application of ultrasound-guided percutaneous biopsy in the preoperative diagnosis and treatment of bone tumors / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To investigate the value of color Doppler ultrasonography (CDUS)-guided percutaneous biopsy in the diagnosis and treatment of bone tumors.@*METHODS@#Ultrasound-guided percutaneous biopsy was performed in 64 patients who was diagnosed by CDUS. Puncture instruments included automatic core biopsy device and 14 to approximately 18G crude needle. All cases were identified by the operation and pathological examination.@*RESULTS@#Tissue-obtained rate was 97% (62/64). Comparing preoperative pathological diagnosis with postoperative pathological diagnosis, we found the diagnostic correct rate was 97%. No complications resulted from this procedure. According to their pathological results, 33 patients were treated with preoperative chemotherapy. The tumor sizes decreased, and 26 patients saved their limbs and had normal functions.@*CONCLUSION@#CDUS-guided percutaneous biopsy is safe and quick for the preoperative diagnosis and selecting appropriate surgical procedure for bone tumor treatment.
