Factors associated with the success of revascularization surgery in diabetic patients with chronic critical limb ischemia

Abstract

Introduction: Revascularizing surgery is one of the fundamental strategies for the treatment of chronic critical ischemia of the lower limbs.Objective: To identify the factors associated with the success of lower limb revascularization surgery in diabetics with chronic critical ischemia.Methods: A descriptive, prospective, cohort-type study was conducted in diabetic patients undergoing revascularization surgery due to chronic critical limb ischemia. The patients were followed for six months at the National Institute of Angiology and Vascular Surgery from September 2019 to January 2021. The primary endpoint variable was the predictor of the success of surgery, which was considered successful when the patient remained alive and without major amputations.Results: 50 patients with an average age of 64 ± 10.21 years and 24 % women were included. 88% of the patients were smokers; and 78% hypertensive ones. The overall effectiveness of surgery was 64% (95% CI 50%-78%). Only the female sex, with a probability of 0.053 and an Odds Ratio of 4.23, history of cerebrovascular disease (p: 0.13 and OR: 6.98); and infection (p: 0.18 and OR: 2.7) showed a tendency to be statistically, significantly associated with the success of surgery.Conclusions: Female sex, history of cerebrovascular disease and presence of infection were the main candidates as prognostic variables of the success of revascularizing surgery.
