A new method for preoperative marking has been evaluated in 56 non-palpable lesions of the breast. With the aid of a stereotaxic biopsy instrument the lesion is located and an aqueous suspension of carbon particles is injected so as to leave a distinct trail from the lesion out to the skin. This trail gives precise guidance to the site of the lesion, facilitating the removal of a minimum volume of tissue. According to current experience, the carbon does not diffuse into surrounding tissues and therefore the marking can be done well in advance of surgery.
一种术前标记的新方法已在56例乳腺不可触及病变中进行了评估。借助立体定向活检仪器定位病变,然后注射碳颗粒水悬液,以便从病变处到皮肤留下明显的痕迹。这条痕迹为病变部位提供了精确的引导,有助于切除最小体积的组织。根据目前的经验,碳不会扩散到周围组织中,因此标记可以在手术前很久就完成。
