超声引导细针定位在乳腺隐匿性病灶切除中的应用

目的 探讨超声引导细针定位在乳腺隐匿性病灶定位切除中的应用价值及其操作技巧。方法 超声引导下细针定位后切除的乳腺隐匿性病灶患者43例共48枚病灶，对其细针穿刺过程、穿刺准确程度进行回顾性分析；同时对细针定位行乳腺区段切除的患者与同期35例行体表标记定位区段切除患者的术后乳房美容效果评价进行对比分析。结果 48枚病灶除两枚针芯穿刺过深外，其余均定位准确。术后3个月超声复查所有病灶均被准确切除。43例患者中4例为恶性肿瘤（9．3％），行全乳切除，其余39例行区段切除术的术后3个月与35例体表定位区段切除术患者美容效果评价，良好者分别为37例（94，87％），24例（68，57％），两者差异有统计学意义（P〈0，01）。结论 超声引导下细针定位简便易行，定位准确，是乳腺隐匿性病灶定位切除较好的方法。

The application of ultrasound-guided wire localization in surgical excision for patients with breast occult lesion

Objective To discuss the value and operational skill of ultrasound-guided wire localization of breast occult lesion. Methods Forty three women with 48 breast occult lesions which were localized by wire under ultrasound guidance before surgical operation.The process and accurate degree of wire localization were analyzed retrospectively. Post-lumpectomy cosmetic results were compared between the patients who were underwent lumpectomy under the ultrasound-guided wire localization and others thirty-five patients who were underwent lumpectomy under the ultrasound-guided surface localization. Results All of the 48 breast occult lesions were accurately localized except 2 lesions in which the wirepoint were located too deeply. After 3 months,all patients were counterchecked by sonography,and no lesion was found.Of 43 cases, cancer was revealed by postoperative pathology in 4 cases(9.3%),all of the 4 cases underwent mastectomy. Cosmetic result was evaluated 3 months after lumpectomy. In the wire localized group,37 of 39 (94.87%)cases had good cosmetic results, while in the group of surface localization,24 of 35 (68.57%)cases had good cosmetic results.There was significant difference between two groups(P<0.01).Conclusion Preoperative ultrasound-guided wire localization appears to be a simple and accurate method for surgical excision for patients with breast occult lesion.
