超声引导下乳腺小肿物的术前定位

目的探讨临床上不可触及的乳腺小肿块术前超声引导下穿刺定位的意义。方法在超声引导下对30例临床上不能触及的乳腺肿块用定位针术前定位。结果 30个临床不能触及的乳腺肿块,术前在超声引导下定位针定位后行外科手术,全部被准确切除,其中3例为（10%）为恶性肿瘤。结论临床上不能触及的乳腺肿块术前行超声引导定位是简单而准确的方法 ,节省了手术时间,组织损伤小,并发症少,减轻患者痛苦。乳腺癌可以在早期被发现。

Preoperative localization of small breast lesion guided by ultrasonography

Objective To explore the value of the located needles guided by ultrasound to locate breast lesions,which were unclear in clinical palpation.Methods Pre-operative localization was performed using wire needle by ultrasonography in 30 non-palpable breast lesion of 30 women.Results Thirty non-palpable breast lesions were excised radically after pre-operation localization guided by ultrasonography.Three（10%）of these lesions were malignant.Conclusion Preoperative localization guided by ultrasonography appear to be a simple method for non-palpable breast lesions.It will save the time of operation,lessen the injury,and at the same,decrease the ratio of complication.The breast cancers could be found by located needles are at small size and at early stage.
