AimsThe goal of the current study was to describe the results of an innovative standardized approach to prevent wound complications in patients with PAD sustaining fractures below the knee.Patients And MethodsIn this retrospective case series, patients submitted to our institution with fractures below the knee, which were treated with endovascular recanalization of relevant stenosis or occlusions prior to definitive open reduction and fracture fixation between January 2015 and December 2019 were included.ResultsOverall 23 patients (mean age 77 ± 9.8 years) were included in the current case series. In five patients (21.7 %) PAD was previously diagnosed. Endovascular interventions were performed 6.9 ± 2.5 days after fracture event and 2.5 ± 1.3 days prior to definitive surgical fixation of the lower limb fracture. After intervention 2 patients had one vessel, 10 patients two vessels and 11 patients three vessels for arterial perfusion of the lower limb. No interventional- radiology procedure related complications were observed. In this case series only two wound infections (8.7 %) occurred.ConclusionEndovascular intervention prior to surgical fixation resulted in a low complication rate after surgical fixation of fractures below the knee in patients with PAD. These results emphasize the crucial role of limb perfusion for adequate wound healing in lower limb fractures. Therefore, examination of limb perfusion should be an integral part of preoperative preparation of patients at high risk for PAD presenting with fractures below the knee. Endovascular recanalization seems to be an appropriate method to prevent wound complications.Copyright © 2021. Published by Elsevier Ltd.
