Abstract: 【Abstract】 Objective To compare the operation time and adverse reactions between two vacuum-assisted breast biopsy system. Methods 100 cases were chosen in outpatient patients and were per-formed ultrasound-guided and vacuum-assisted needle biopsy（VANB）in our hospital from March 2015 to June 2015. Fifty cases were performed surgery by VANB system A and another 50 patients by VANB system B. The operation time（from lesion position to the end of the operation）, blood loss, preoperative and postoperative D-value of highest heart rate and systolic blood pressure, hematoma volume and postop-erative breast profile were observed and compared between two groups. Results Systolic blood pres-sure, heart rate changing, postoperative hematoma of magnitude breast appearance between system A and B had no significant difference. The operation time of the system A was 8.7+5.39 min, and was sig-nificantly less than that of the system B group（17.56+8.63 min, P<0.05）。 Amount of bleeding system A was 3.7±2.6 ml significantly and was less than that of system B（6.1±3.9 ml, P<0.01）. Conclusion System A showed shorter operation time and less bleeding amount in the breast biopsy.
