Ultrasound-guided coaxial aspiration for retrieval and repositioning of breast localization markers

Breast localization marker migration or malposition may create a practical need for image-guided retrieval or repositioning. The technique was performed in two patients using a coaxial needle system and aspiration-assisted marker capture. In both cases, the displaced marker was identified sonographically and accessed with a coaxial needle. Controlled aspiration drew the marker into the coaxial needle, followed by repositioning to the targeted area or removal from the body. No immediate complications occurred. Ultrasound-guided coaxial aspiration may represent an alternative in selected cases of migrated or malpositioned markers when standard vacuum-assisted excision is technically disadvantageous.
