SAVI SCOUT® Radar Localization of Breast Lesions as a Practical Alternative to Wires in Breast Cancer and Macromastia. Description of Our Experience with the Use of Radar Localization System

Breast cancer is a leading cause of cancer-related deaths among females in the world.Image-guided wire localization (WL) of non-palpable breast lesions has traditionally been used to help surgeons localize these tumours.WL is normally carried out the same day as the surgical procedure, which can lead to programming conflicts between the radiological and surgical teams.New devices have been developed to help overcome the disadvantages related to WL.One of them is the SAVI SCOUT® system (SS), a surgical guidance system, nonradioactive infrared activated electromagnetic wave reflector that can be implanted into the breast under imaging guidance the same day as the biopsy and remain until the day of surgery, even if the patient initially undergoes neoadjuvant therapy.Very little training is required for the radiologist.We report the case of a 75-year-old woman with breast cancer and macromastia.The ultrasound and mammography described two lesions in the left breast associated with a wide area of micro calcifications between both lesions (about 4cm).Two SS reflectors were placed identifying both lesions and delimiting the suspicious area of micro calcifications.Bilateral oncoplastic reduction mammoplasty was performed.In addition, a descriptive review of the results obtained in breast conservation surgery using SS from August to December 2022 was also performed.SS was used in 40 patients of the 130 patients (43%) who underwent breast cancer surgery.All SS reflectors were detected and removed.In 2 cases, the radar localization system stopped working after direct contact of the SS reflector with the electric scalpel.
