PURPOSE: Chronic limb-threatening ischemia due to isolated below-the-knee lesions is a factor associated with wound recurrence. However, there is a lack of data regarding wound recurrence in such cases. This study aimed to determine the predictors of wound recurrence in patients with chronic limb-threatening ischemia undergoing endovascular treatment.
PATIENTS AND METHODS: This was a single-center, retrospective, observational study. We enrolled 152 consecutive patients with chronic limb-threatening ischemia (172 limbs) who achieved complete wound healing after undergoing endovascular treatment for isolated below-the-knee lesions between February 2008 and December 2017. Of these, the wound had recurred in 56 limbs (33%), and we divided the patients into 2 groups based on wound recurrence. We evaluated the recurrence rate of chronic limb-threatening ischemia and predictors of wound recurrence. Wound recurrence was defined as recurrence of the wound within 2 years of complete wound healing.
RESULTS: Patients' backgrounds were similar in both groups, including mean age (72±9 vs 72±11; p=0.76) and hemodialysis (43% vs 40%; p=0.66). Pre-pedal arch type 2 (52% vs 8%; p<0.01), infrapopliteal grade 4 of the Global Limb Anatomic Staging System (77% vs 59%; p=0.02), and Wound, Ischemia, and foot Infection criteria stage 4 (43% vs 28%; p=0.04) were more common in the wound recurrence group. Multivariate Cox proportional hazard analysis identified pre-pedal arch type 2 (hazard ratio, 5.28; 95% confidence interval, 3.08-9.10; p<0.01) and Wound, Ischemia, and foot Infection criteria stage 4 (hazard ratio, 1.98; 95% confidence interval, 1.15-3.36; p=0.01) as predictors of wound recurrence after complete wound healing.
CONCLUSION: Pre-pedal arch type 2 and Wound, Ischemia, and foot Infection classification system stage 4 were associated with wound recurrence in patients with chronic limb-threatening ischemia who achieved complete wound healing after undergoing endovascular treatment for isolated below-the-knee lesions.
