Reliability of reverse sural artery fasciocutaneous flap in older adult patients: Comparison study between older and younger patients

초록

Background: The reverse sural artery fasciocutaneous (RSAF) flap is a popular option for patients with soft tissue defects of the distal lower extremities. However, most studies have focused on young patients without comor-bidities. This study aimed to report the clinical application of the RSAF flap and to evaluate its reliability in older adult patients. Methods: A retrospective study of fifty-one patients who underwent RSAF flap was included in this study between September 2016 and October 2021. Reconstruction outcomes and wound complications were compared between groups A (21 patients over 60 years of age) and B (30 patients under 60 years of age). Results: Overall, 74.5% of the flaps healed primarily. The demographics of the two groups were similar, except for comorbidities (P = 0.01). The risk factors that affected the survival of RSAF flaps were not significantly different between the two groups (P > 0.05). The rate of wound complications in group A (42.85%) was significantly higher than that in group B (13.3%) (P = 0.04). However, all wound complications were treated using a simple procedure (skin grafting or simple suturing). Conclusions: The RSAF flap can be a reliable salvage option to repair soft tissue defects of the lower extremities in older adult patients. It is safe and easy to harvest and transfer the flap; however, surgeons should be aware of the possibility of wound complications in older patients with comorbidities.
