Preoperative Wire Localization of the Breast on the Day Before Surgery

Area of Science:

• Radiology
• Surgical Oncology

Background:

• Preoperative wire localization is crucial for guiding breast lesion excision.
• Optimizing the timing and technique of wire placement can improve procedural efficiency and patient outcomes.

Purpose of the Study:

• To evaluate the feasibility and accuracy of same-day preoperative wire localization.
• To assess the impact of the time interval between wire placement and surgery on wire migration.
• To compare the migration distances of hooked versus looped wires.

Main Methods:

• Two trials involving mammography assessed wire migration with hooked (Trial 1) and looped (Trial 2) wires.
• A third trial used the looped wire without repeat mammography.
• Statistical analyses compared migration distances and directions between wire types.

Main Results:

• No wires required repositioning on the day of surgery.
• Looped wires showed significantly less migration (0-7 mm) than hooked wires (0-18 mm).
• No correlation was found between the time interval and migration distance.

Conclusions:

• Same-day preoperative wire localization is a feasible, accurate, and cost-effective procedure.
• The looped wire design minimizes migration, potentially eliminating the need for repeat imaging.
• This approach effectively separates radiologic and surgical workflows.
