Immediate and long-term complications of direct-to-implant breast reconstruction after nipple- or skin-sparing mastectomy

Background: Traditionally, breast reconstruction options after mastectomy comprise an autologous flap or staged expander/implant reconstruction, or a combination of both. Recent introduction of skin or nipple-sparing mastectomies have led to much interest in direct-to-implant immediate breast reconstructions. We performed a retrospective review of our initial experience.

Methods: Between June 1998 and December 2010, 31 of 671 patients (4.6%) who received implant-only breast reconstruction underwent direct-to-implant immediate breast reconstruction after mastectomy for primary or recurrent cancers, or risk reduction. Their files were audited, and the primary factor examined was the failure of reconstruction with loss of prosthesis. Other complications, revision surgery, and aesthetic result are also recorded.

Results: The mean follow-up period for the 31 patients was 49.5 months. A total of 45 mastectomies were performed for 21 primary and 4 recurrent breast cancers after previous conservation surgery and radiotherapy (RT), and 20 for risk reduction. Ten patients received RT (4 before mastectomy and 6 afterward). Average size of implants was 380.0g (range, 205-620g). The most common postoperative complications were seromas (20%); only 1 implant was lost (2.22%). Nineteen breasts required revision surgery after 6 months with 1 more implant lost. Despite the high revision rate, 28 (90.3%) had excellent or good aesthetic result.

Conclusions: Immediate single-stage direct-to-implant breast reconstruction has a high rate of both immediate postoperative complications and revisions after 6 months, especially after RT. However, most complications are manageable and do not necessarily result in implant loss. Most cases can have a successful outcome without implant loss with excellent or good cosmetic results.
