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.

摘要： 【摘要】目的比较目前常用的两种真空辅助乳腺活检系统在手术耗时及不良反应情况。方法选择我院2015年3月～6月于门诊手术室进行超声引导真空辅助活检术的女性，分别采用目前临床使用的两种（系统A和系统B）进行手术，每组各50例。分别记录手术耗时（从定位到手术结束），出血量，术前与术中收缩压最高值差值（△收缩压）和心率最高值差值（△心率），血肿数量以及乳房外形。结果系统A与系统B的△收缩压，△心率，术后血肿数量级乳房外观均无明显统计学差异，P>0.05。系统A的手术时间为8.7±5.39分，明显少于系统B的17.56±8.63分，存在统计学差异，P<0.05；系统A的术中出血量为3.7±2.6mL，明显少于系统B的6.1±3.9mL，同样存在统计学差异，P<0.01。结论系统A用于乳腺真空活检具有手术耗时少，出血量低的优势，可在乳腺活检中进行推广。
