Abstract

Overview: The WIfI score was first introduced as an initial assessment, helping to predict the risk of limb amputation, the feasibility, and the benefit of revascularization in patients with chronic limb-threatening ischemia.


Objectives:  Determining the correlation between WIfI score and the outcome of endovascular intervention in the lower limb in chronic ischemia threatening limb stage.


Methods: A retrospective study was conducted to identify the cases with chronic limb threatening ischemia of the infrainguinal artery occlusion, treated by endovascular intervention at the Department of Vascular Surgery, Cho Ray Hospital from August 2020 to May 2021.


Results: There were 80 patients with 80 limbs that were treated, with mean age of 71.5, male gender accounted for 67.5%. Patients were admitted to the hospital with Rutherford stages 4,5,6 respectively 42.5%, 42.5% and 15%. WIfI stages 1,2,3,4 respectively 6.3%, 46.3%, 23.8%, 23.8%. The technical success rate was 96.3%, the wound healing rate was 79.1%, the primary patency rate was 64.9%, the limb salvage rate was 89.7%, the survival rate was 97.5%. The higher WIfI stage before intervention was associated with lower primary patency and limb salvage rates, statistically significant with p<0.05. There was no correlation between WIfI stage and mortality rate.


Conclusions: The WIfI classification system is very important in chronic limb-threatening ischemia, as it helps to estimate the limb salvage rate, predict the need for revascularization and wound healing.
