The role of percutaneous CT-guided vertebral biopsy using bone marrow biopsy needle combine with semi-automatic soft tissue biopsy needle

SUMMARY

Introduction: The bone biopsy instruments were improved regularly to increase successful rate and reduce complication but accompany with increasing of cost price. Our research purpose to assess the role of percutaneous CT-guided vertebral biopsy using bone marrow biopsy needle combine with semi-automatic soft tissue biopsy needle.

Method: This is a retrospective study involving 143 patients who underwent percutaneous CT-guided vertebral biopsy in Radiology department, Bach Mai hospital. Biopsy needle included: bone marrow biopsy needle 13 and 11G, Surelock, TSK, Japan combined with soft tissue biopsy needle Stericut 16 and 14 G, TSK, Japan. Result: Adequacy 95.1%, pathologic specific diagnosis rate 86%, accuracy 85.3% and complication rate 0.7%.

Conclusion: The adequacy of technique is not lower than most recent researches as so as open vertebral biopsy, the complication rate is not higher than most recent researches but significant lower than vertebral open biopsy.
