Risk Factors for Donor-Site Seroma Formation After Immediate Breast Reconstruction With the Extended Latissimus Dorsi Flap

Abstract

The extended latissimus dorsi flap has been widely used for breast reconstruction. However, seroma at the donor site is a common complication and makes it difficult for reconstructive surgeons to choose it as a primary option. We analyzed the association between seroma and reconstructions with extended latissimus dorsi flaps. A series of 120 consecutive cases were included in this study. The average body mass index (BMI) was 22.1 kg/m, and the mean ratio of the flap weight to the extirpated breast weight was equivalent to 101.6%. The mean age of patients was 40.3 years. Donor-site seroma was reported in 69.2% (83 cases) of the total patients. With respect to BMI, flap weight, and age, the incidence and duration of donor-site seroma showed statistically significant differences (P<0.05). Both the incidence and duration of seroma were significantly higher and longer in patients who had high BMI (>23 kg/m), large flap (>450 g) for reconstructions, or advanced age (>45 y). In these cases, greater attention and additional adjunctive procedures would be needed to prevent seroma.
