Summary
The new VacuFlash (VF) breast biopsy system offers a technically advanced, integrated approach for tissue sampling. Preliminary results show it is applicable for diagnosing breast lesions, with complete removal observed in some cases.
Area of Science:
- Medical Imaging and Interventional Radiology
- Breast Pathology and Diagnostics
Background:
- Stereotaxic and sonographically guided vacuum biopsies are established interventional breast procedures.
- Existing systems like Mammotome require separate components for vacuum biopsy.
Purpose of the Study:
- To report preliminary findings on a novel sonographically guided, vacuum-assisted breast biopsy system: VacuFlash (VF).
- To compare the integrated design of the VF system with existing vacuum biopsy devices.
Main Methods:
- The VacuFlash (VF) system, featuring integrated vacuum biopsy components in a hand-held gun, was used.
- VF biopsy was performed on five patients with nonpalpable, sonographically detectable breast lesions.
Main Results:
- Histopathological examination diagnosed fibroadenoma in 4 patients and unremarkable breast parenchyma in 1 patient.
- Immediate post-biopsy sonography indicated complete removal of the lesion in 3 out of 5 patients.
Conclusions:
- The VacuFlash (VF) biopsy system is a new, applicable diagnostic method for breast lesions.
- Further comparison with other methods like high-speed core cut biopsy is needed regarding costs, risks, and accuracy.
- Indications include lesions unsuitable for conventional core biopsy or those requiring wide sampling; complete removal is feasible for small lesions.
