Abstract

Background: Secondary breast reconstruction (BR) is recognized as a challenging procedure, particularly when radiotherapy (RT) has previously been performed. The aim of this study was to compare operative data and aesthetic outcomes between secondary irradiated and immediate BR using the fat-augmented latissimus dorsi (FALD) flap. Methods: The authors conducted a prospective clinical study between September of 2020 and September of 2021. Patients were divided into two groups: group A included secondary BR using the FALD flap in previously irradiated breasts, and group B included immediate BR with the FALD flap. Demographics and surgical data were compared, and an aesthetic analysis was performed. Chi-square and t tests were performed for categorical and continuous variables, respectively. Results: Twenty cases of FALD flap-based BR for each group were included. The two groups were found to be homogeneous for the demographic variables. The difference in mean operative time (263.1 minutes versus 265.1 minutes; P = 0.467) and complications (P = 0.633) between the two groups were not significant. There was statistically significant difference in term of immediate fat grafting volume in favor of group A (218.2 cc versus 133.0 cc; P < 0.0001). Regarding aesthetic outcomes, the mean global score evaluation showed no statistically significant differences between groups (17.86 versus 18.21; P = 0.209). Conclusions: The authors’ study states that the FALD flap can be considered a reliable procedure for secondary reconstruction in previously irradiated breasts, although it is not indicated for patients with larger breasts. This surgical technique allowed us to achieve a totally autologous BR with good aesthetic results and low complication rates, even in secondary irradiated cases. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.
