We present our initial experience of ultrasound (US)-guided localization of clipped metastatic axillary lymph nodes (LNs) following neoadjuvant chemotherapy (NAC). We evaluated US visibility and the successful excision rate of clipped LN after NAC in 29 consecutive patients with breast cancer. US-guided localization of clipped nodes was performed in 22 patients on the day of surgery, while seven patients underwent surgery without localization. The clips were identified in all patients with residual metastatic LNs and 6 of 12 (50%) patients without residual metastatic LNs on US. Six patients without visible clips underwent US-guided localization at the presumed previous clip insertion site. The successful excision rate of 22 LNs with localization was 100% (even though 3 of them were non-sentinel LNs) and 57% (4/7) without localization. Regardless of the presence of visible residual metastatic LNs on US after NAC, successful excision of the clipped LN with US-guided localization is feasible.
我们展示了我们在新辅助化疗（NAC）后对夹闭的转移性腋窝淋巴结（LN）进行超声（US）引导定位的初步经验。我们评估了29例连续乳腺癌患者在NAC后US对夹闭LN的可见性以及夹闭LN的成功切除率。22例患者在手术当天进行了US引导下夹闭淋巴结的定位，而7例患者未进行定位直接接受了手术。在所有有残留转移性LN的患者以及12例无残留转移性LN患者中的6例（50%）中，US均识别出了夹子。6例未见到夹子的患者在推测的先前夹子插入部位接受了US引导定位。22例经定位的LN的成功切除率为100%（尽管其中3个是非前哨LN），未定位的成功率为57%（4/7）。无论NAC后US上是否存在可见的残留转移性LN，通过US引导定位成功切除夹闭的LN都是可行的。
