Effect of endovascular revascularization of pedal artery on healing of the wound in patients with chronic limb-threatening ischemia

Authors

Abstract

Introduction
Disease of the pedal artery is one of the most significant predictors of wound healing, so endovascular pedal artery revascularization (PAR) may affect the extent and speed of wound healing.
Patients and methods
All of the patients in this study had infrapopliteal and pedal artery diseases and chronic limb-threatening ischemia. The patients were divided into two groups: one with endovascular PAR and the other without PAR. Comparisons of the timing and rate of wound healing between the two groups were made.
Results
The research involved 42 individuals: 20 patients did not get PAR, whereas the other 22 patients underwent PAR. Results regarding timing of wound healing was shorter in the group with PAR than in the group without PAR (92.0±12.6 vs. 143.0±53.2 days), and the wound healing rate was greater in the group with PAR than in the group without PAR (89 vs. 61%).
Conclusion
Endovascular PAR in patients with chronic limb-threatening ischemia has an excellent effect on limb salvage as it improves the rate and timing of wound healing.
