Abstract

Aim

Stereotactic-guided vacuum-assisted biopsy (STVAB) is the standard of care to biopsy mammographically detected breast lesions without a sonographic correlate. It can be performed using the conventional (CBA) or lateral-arm biopsy approach (LABA). Tissue marker (clip) placement is routinely done post-biopsy. Clip migration is frequently encountered in STVAB and can result in higher rates of positive margins and re-excision in subsequent surgery. We sought to compare clip migration rates between CBA and LABA.

Materials and methods

We performed a retrospective review of 347 cases performed at an Asian institution from 2021 to 2024, on predominantly dense breasts. We compared clip migration rates between CBA and LABA. Other factors that were known to contribute to clip migration were also studied, including breast density and hematoma size. Statistical analysis was done using Fisher's exact test, Mann–Whitney U test and linear regression models.

Results

A total of 347 biopsies were performed. CBA was performed for 297 (85.6 %) patients and LABA was performed for 50 (14.4 %). LABA was found to significantly reduce clip migration rates compared to CBA (4 % versus 25.9 %, p < 0.001). Breast density (p = 0.55) andhematoma size (p = 0.662) were not found to significantly affect clip migration rates.

Conclusion

We recommend utilizing LABA over CBA whenever technically possible if we wish to minimize clip migration.

期刊介绍： The mission of Clinical Imaging is to publish, in a timely manner, the very best radiology research from the United States and around the world with special attention to the impact of medical imaging on patient care. The journal''s publications cover all imaging modalities, radiology issues related to patients, policy and practice improvements, and clinically-oriented imaging physics and informatics. The journal is a valuable resource for practicing radiologists, radiologists-in-training and other clinicians with an interest in imaging. Papers are carefully peer-reviewed and selected by our experienced subject editors who are leading experts spanning the range of imaging sub-specialties, which include: -Body Imaging- Breast Imaging- Cardiothoracic Imaging- Imaging Physics and Informatics- Molecular Imaging and Nuclear Medicine- Musculoskeletal and Emergency Imaging- Neuroradiology- Practice, Policy & Education- Pediatric Imaging- Vascular and Interventional Radiology
