[IATROGENIC INJURIES DURING PREOPERATIVE MARKING OF NON-PALPABLE PATHOLOGICAL AREAS OF THE MAMMARY GLANDS].

The purpose of the study is to identify the types and frequency of medical mistakes made during preoperative marking of non - palpable pathological areas of the breast. We analyzed 60 clinical observations of patients with non-palpable, morphologically verified pathological areas in breast tissues, who underwent surgical intervention at the first stage of treatment with mandatory preoperative marking with a guide needle. The obtained data indicates that the error rate of radiologists when installing a tissue marker in a non-palpable breast neoplasm is 13.3% and is most often manifested by syntopia of the guide needle, which is detected at the beginning of the operation and requires implantation of additional tags. All clinical observations were accompanied by an increase in both the equivalent dose received by the patient and duration of the anesthesia. To improve the quality of interventional techniques performed on the breast, also to minimize the number of iatrogenic injuries, the radiologist must have spatial thinking, a sufficient amount of theoretical knowledge and practical skills.
