Placement of an EnVisio SmartClip® in the Breast Using CT-Guidance: A Case Report

A bstract Management of non-palpable, clinically occult breast cancers typically involves placement of a marker clip at the time of biopsy, followed by a localisation procedure, typically wire-guided localisation, the day of or the day before surgery to guide excision. Newer techniques for the localisation step are becoming increasingly popular given their many potential advantages over using a wire. Here, we present a case for which wire-guided localisation was deferred due to the inability to visualise the marker clip using mammography. An electromagnetic-guided localisation device using computed tomography guidance was used to enable accurate localisation of the breast lesion. This case highlights the potential of electromagnetic-guided localisation methods as an alternative when traditional methods fail and raises the consideration for its broader feasibility in replacing conventional localisation techniques.
