The Vacuum-Assisted Breast Biopsy System is an Effective Treatment Strategy for Breast Lumps After Augmentation with Autologous Fat Grafting

Background With the extensive application of autologous fat grafting (AFG) to the breasts, postoperative complications such as breast lumps attract high attention. Breast lumps greatly reduce patient satisfaction and bring mental stress. However, there are few detailed reports about minimally invasive treatment strategies for breast lumps after AFG. Our study aimed to investigate the effectiveness of the vacuum-assisted breast biopsy (VABB) system for patients with lumps after AFG. Materials and Methods We retrospectively reviewed 37 patients with breast lumps between April 2015 and January 2019. The characteristics of patients and breast lumps were analyzed. Breast lumps were classified into four types, including cystic, solid, complex and calcification. The vacuum-assisted breast biopsy (Mammotome and Encor) was performed for the patients with lumps after AFG. The efficacy, safety, complications and patient satisfactions were recorded during postoperative follow-up periods. Results Under the guidance of ultrasound, the breast lumps could be thoroughly and accurately excised by the vacuum-assisted biopsy system. No patient experienced breast infections or major complications requiring treatment. Hematoma was observed in only 2 patients and gradually resolved without any special management. With a median follow-up of 29 months, no recurrence was observed. Furthermore, there were no statistical differences in duration of the procedures and complications between the two VABB systems. All the patients recovered well and were satisfied with the cosmetic outcome. Conclusion The vacuum-assisted breast biopsy system can be used as an effective and minimally invasive approach for the surgical management of lumps after AFG.
