The indications for microsurgical breast reconstruction remain debated, particularly concerning the safety of deep inferior epigastric perforator (DIEP) flaps in elderly women. Free tissue transfer still carries a risk of perioperative morbidity and mortality in elderly patients. We conducted this comparative study to clarify this issue.
This retrospective cohort study included all unilateral DIEP breast reconstructions performed at a single institution. Patients were divided into two groups based on age: an elderly (60 years or older) and a non-elderly cohort (younger than 60 years). Demographic and comorbidity data were secondary predictor variables. The primary outcomes were complete flap loss, partial flap loss, and the need for flap re-exploration. The secondary outcomes included surgical site occurrences, such as wound healing-related complications, seroma, and others.
We included 214 flaps, 177 in the non-elderly and 37 in the elderly cohort. Elderly women had slightly higher comorbidity rates than those of non-elderly women, although these differences were not statistically significant. BMI was significantly lower in elderly women than in non-elderly women. The incidence of total or partial flap loss did not differ significantly between the two cohorts (2.7% vs 1.1%, p = 0.459% and 0.0% vs 5.1%, p = 0.161), nor did the flap re-exploration (8.1% vs 10.1%, p = 0.937). Similarly, postoperative complication rates did not differ significantly between the two groups (45.9% vs 61.8%, p = 0.074). On logistic regression, being elderly was not a risk factor for complete flap loss, nor for any complications. The overall success rate for the non-elderly cohort was 98.7%, whereas that for the elderly cohort was 97.3%.
Microsurgical breast reconstruction using DIEP is safe in elderly patients, as it achieves outcomes and complications rates comparable to those observed in a younger population. Patients should not be denied DIEP flaps because of their age alone.
