Background: Acellular dermal matrices (ADMs) are sometimes used in implant-based breast reconstructions (IBR), but long-term ADM-related evaluations are scarce. In this study, we evaluated early and late complications and patient-related outcomes (PROs) over an 8-year postoperative period in women who had undergone immediate IBR following risk-reducing mastectomy with bovine ADM (SurgiMend). Methods: This prospective observational single-center analysis involved 34 women at high risk for breast carcinoma. Complications were prospectively recorded during the first year, followed by 4 years of postoperative retrospective chart reviews. Long-term evaluations were done using a questionnaire. Preoperative, 1 year, and 5- to 8-year postoperative PRO assessments were obtained based on results from the BREAST-Q questionnaire. Results: In 56 breasts, complications after a mean of 12.4 months follow-up included implant loss (7.1%), implant change (1.8%), hematoma (7.1%), breast redness (41.1%), and seroma (8.9%). Most breasts (80.3%) were graded Baker I/II, which indicated a low capsular contracture incidence. After a mean of 6.9 years, the total implant explantation rate was 33.9%, and the revision surgery rate was 21.4%. Two cases of breast cancer were reported during the long-term evaluation. BREAST-Q results indicated significantly decreased satisfaction with outcome ( P = 0.024). A positive trend regarding psychosocial well-being and declining trend regarding satisfaction with both breast physical- and sexual well-being parameters were reported. Conclusions: The observed complication rates agree with previous findings concerning ADM-assisted IBR. A high demand for revision surgery exists, and PROs remain relatively stable over time.
