The purpose of this study was to evaluate the role of US guided hand held vacuum-assisted breast core biopsy (VACB) in the surgical management of breast nodules.
Twenty five breast nodules in twenty five women were subjected to US guided 11-gauge vacuum-assisted breast core biopsy over a period 22 months. Biopsies were performed using handheld 11-g VACB needle under US guidance using high-resolution US equipment with a 7.5-10 MHz linear transducer. A median of 12 specimens were obtained per lesion with insertion of a clip marker in place. Pre and post procedure imaging findings, complications, histologic outcome, and medical records were reviewed.
The patient median age was 50.16 years (range, 36- 72 years). Lesion median size was 1.7 cm (range 0.8-3.0 cm). Lesions were categorized using BI-RAD system as follow: 12 (48%) category 3, 11 (44%) category 4 and 2 (8%) as category 5. Six out of 25 (24%) lesions were palpable. The median time required to perform the biopsy was 25 min (range, 20-40 min). Complete removal of the lesion seen at sonography was achieved in 22/25 lesions (88%) and was significantly more frequent in lesions measuring < 1.5 cm than in larger lesions. Accuracy was 100 %. No repeat was asked. Surgical biopsy was spared in 24/25 (96%) patients. One case was referred for surgical excision upon pathologist advice.
In our small series, US guided vacuum-assisted beast core biopsy was a fast, less invasive, accurate method in diagnosing breast nodules. It is a cost effective procedure, accepted by the patient and led to sparing surgical procedure in 96 % of women. VACB has become an integral part in the management of breast nodules and further work is going on to assess the long-term outcome.
本研究旨在评估超声引导下手持式真空辅助乳腺粗针活检（VACB）在乳腺结节手术治疗中的作用。
在22个月的时间里，对25名女性的25个乳腺结节进行了超声引导下11号真空辅助乳腺粗针活检。活检采用手持式11号VACB针，在超声引导下使用配备7.5 - 10 MHz线性换能器的高分辨率超声设备进行。每个病灶平均获取12个标本，并放置一个夹式标记物。回顾了术前和术后的影像学表现、并发症、组织学结果及病历资料。
患者的中位年龄为50.16岁（范围36 - 72岁）。病灶的中位大小为1.7 cm（范围0.8 - 3.0 cm）。根据BI - RAD系统对病灶进行分类如下：3类12个（48%），4类11个（44%），5类2个（8%）。25个病灶中有6个（24%）可触及。进行活检所需的中位时间为25分钟（范围20 - 40分钟）。25个病灶中有22个（88%）在超声检查中实现了病灶的完全切除，且直径<1.5 cm的病灶比更大的病灶更常实现完全切除。准确率为100%。无需重复活检。25名患者中有24名（96%）避免了手术活检。1例根据病理学家的建议接受了手术切除。
在我们的小样本研究中，超声引导下真空辅助乳腺粗针活检是诊断乳腺结节的一种快速、微创且准确的方法。它是一种经济有效的检查方法，患者易于接受，96%的女性因此避免了手术。VACB已成为乳腺结节治疗中不可或缺的一部分，目前正在进一步开展工作以评估其长期效果。
