超声引导金属弹簧圈定位乳腺肿块的临床应用

目的探讨乳腺肿块金属弹簧圈标记的临床应用价值。方法对13例触诊不清的乳腺良性肿块,41例新辅助化疗的乳腺癌,在超声引导下行术前边界定位及肿块标记。事先测量好肿块最大直径,选择相应长度的金属弹簧圈,通过18G穿刺针,用导丝准确将弹簧圈放入肿物最大切面两极。41例乳腺癌定位后继续化疗2~3个周期。结果13例触诊不清的乳腺良性肿块连同其内的弹簧圈被准确、完整切除。41例乳腺癌中,术后弹簧圈周边即肿物切缘病理未见残留癌细胞术前化疗期间,经超声观察,39例肿块缩小,其中9例术前超声显示肿物边界已显示不清,只显示金属弹簧圈,这其中3例术后肿物连续病理切片,证实未见癌细胞。结论超声引导下金属弹簧圈肿物边缘定位,对触诊不清的乳腺肿块边界定位是一种新方法。特别是对于术前化疗的乳腺癌患者,在肿块超声随访、化疗疗效评价以及指导术后病理取材部位等方面有更实用的临床意义。

Localization of Breast Lesions Using Metal Spring Ring under the Guidance of Ultrasonography

Objective To evaluate the value of metal spring ring for localization of breast lesions. Methods Thirteen cases of nonpalpable breast benign lesion and 41 cases of breast cancer that had been treated by neoadjuvant chemotherapy were enrolled in this study. The lesion was localized with the margin being marked under the guidance of ultrasonography. Metal spring rings with proper length was used according to the maximum diameter of the lesion; and then via a 18G puncture needle, the metal spring ring was plac...
