Highlights
- •SAVI SCOUT® is successfully used for breast localizations in most cases.
- •Single excisions, bracketing and axillary lymph nodes are all amenable to SCOUT®.
- •The most common issue encountered was difficulty in obtaining an audible signal.
- •Audible signal difficulties are attributed to depth, hematoma or faulty reflector.
Abstract
Objective
The purpose of our study was to determine the frequency of successful SAVI SCOUT®
localizations, to identify the factors contributing to unsuccessful procedures, and
to provide a problem-solving algorithm to address those factors.
Subjects and methods
This retrospective study was performed following IRB approval. We included all consecutive
patients with SCOUT® reflector placement performed at a single tertiary-care cancer
center. Each case was reviewed and the following data were recorded: patient age,
breast density, localization target, imaging modality used for guidance, post procedure
mammogram reflector to skin and reflector to target distances, presence of the reflector
in the specimen radiograph, excisional biopsy pathology and any procedure complications.
Results
In 129 women, 152 SAVI SCOUT® reflectors were placed. Most patients had only 1 reflector
placed, but 19 (15%) women had multiple reflectors placed for the purposes of bracketing,
multiple excisions in 1 breast, bilateral excisions, or any combination thereof. The
most common target was a mass (65%) and the most common modality for guidance was
ultrasound (73%). SAVI SCOUT® localization was successful in 97%of reflectors, including
89% of reflectors targeting axillary lymph nodes. The most common failure encountered
was the inability to obtain a signal in the radiology suite, due to (1) excessive
target depth for the radiology suite handpiece and console, (2) obscuration by a hematoma,
or (3) faulty reflector. No post-operative complications occurred.
Conclusion
The SAVI SCOUT® surgical guidance system is an accurate and reliable method for localization
of non-palpable breast lesions, bracketing, and axillary lymph nodes.
