METHOD OF DETERMINING OPERATION ACCESS FOR BIOPSY OF NON-PALPABLE BREAST LESIONS Russian patent published in 2010 - IPC A61B17/00 A61B8/08 

FIELD: medicine.

SUBSTANCE: invention relates to surgery and can be applied for determining operation access for biopsy of non-palpable breast lesions. Pre-operation ultrasonomammography is performed in supine position with homolateral arm behind the head, identical to the following patient's position on operation table. Ultrasonic topometry of non-palpable lesion is carried out. Longitudinal scanning of lesion, in place where marked edge of sensor corresponds to lesion edges mark is made on skin by means of dye, obtaining projection of lesion length. Transverse scanning is carried out, in place where marked edge of sensor corresponds to lesion edges mark on skin with dye is made and projection of lesion diametre is obtained. Lesion contours are plotted on skin by means of dye. Data about depth of lesion location are analysed. Localisation of planned skin cut, its form, length, value of indent from lesion edges are determined and line of planned cut is drawn on skin by means of dye.

EFFECT: method allows to reduce risk of stimulation of tumour process generalisation, reduce operation trauma.
