Limitations
VTE
COMPLICATIONS
This study has study several drawbacks. First, this study only investigated the early prognosis of applying VFP to prevent VTE; the follow-up was only three days after surgery, while relative long-term outcomes were not evaluated in the study. Second, this study did not assess the occurrence of complications such as skin pressure injuries, which is crucial to ensure the safety of VFP for the duration of application. Thus, validation studies are still warranted in the future. Finally, due to the small sample size of this study, no definite conclusion can be drawn. In the future, multi-center studies with large samples are needed to provide more robust evidence for the standardized application of plantar venous pumps in clinical practice.
