Abstract
Background: chronic limb-threatening ischemia represents the most severe form of peripheral arterial disease and is strongly associated with reduced survival and limb salvage rates. Classification systems are essential for clinical decision making as well as setting meaningful goals and expectations with patients and their families. The Society for Vascular Surgery has proposed the Wound, Ischemia, and foot Infection (WIFI) classification system as a prognostic tool for amputation risk in patients with chronic limb threatening ischemia (CLTI).
Aim of the work: To assess the applicability of WIFI classification in prediction of limb salvage in patients with chronic Limb Threatening Ischemia (rest pain, ulcers or gangrene).
Patients and Methods: This a prospective observational cohort study. 40 patients presented with critical limb ischemia between January 2020 to December 2021 in Ain Shams University hospitals, were treated by infra-inguinal peripheral angioplasty. The Study assess the applicability of WIFI classification in prediction of limb salvage.
Results: The study was done on 40 patients which all have critical limb ischemia, there were 9 females (22.5%) and 31 males (77.5), the age ranged between 45 years and 73 years with mean age of 61.75 years ±7.32 SD. 11 patients required major amputation (27.5%); 31 (72.5%) had limb salvage. Amputation rates were: 0% for WIFI stage 1, 9.1% for WIFI stage 2, 9.1% for WIFI stage 3 and 81.8 % for WIFI stage 4. The amputation group had a significantly higher prevalence of stage 4 patients (P < .001), whereas the limb salvage group presented predominantly as stages 1 to 3.
Conclusion: WIFI classification could be useful to predict possibility of amputation in patients presented with chronic limb threatening ischemia.
