Mean mammographic target to reflector distance was 0.3 cm.
By using statistics software, descriptive statistics were generated with 95% confidence intervals (CIs) calculated. Re-excision rates and complications were recorded. Target to reflector distance was measured on the mammogram and radiograph of the specimen, and reflector depth was measured on the mammogram.
Radiographs of the specimen and pathologic analysis helped verify target and reflector removal. Target and reflector were localized intraoperatively by one of two breast surgeons who used a handpiece that emitted infrared light and electromagnetic waves. Twenty patients had two or three reflectors placed for bracketing or for localizing multiple lesions, and when ipsilateral, they were placed as close as 2.6 cm apart. By using image guidance 0-8 days before surgery, 123 nonradioactive, infrared-activated, electromagnetic wave reflectors were percutaneously inserted adjacent to or within 111 breast targets. Materials and Methods A single-institution retrospective review of 100 women who underwent breast lesion localization and excision by using the Savi Scout surgical guidance system from June 2015 to May 2016 was performed. Purpose To evaluate outcomes of Savi Scout (Cianna Medical, Aliso Viejo, Calif) reflector-guided localization and excision of breast lesions by analyzing reflector placement, localization, and removal, along with target excision and rates of repeat excision (referred to as re-excision).
