Background: Critical lower limb ischemia is defined as a clinical syndrome of ischemic pain at rest and loss of tissue, associated with ulcers that are difficult to heal, and/or gangrene. There are currently multiple interventions in vascular surgery that can improve prognosis. We pretended to describe the clinical outcomes in patients with critical lower limb ischemia undergoing lower limb revascularization in a highly complex institution, during the period 2018-2019. Methods: A cross-sectional study was performed, in which we included all patients with chronic lower limb ischemia who were electively brought to lower limb revascularization from January 2018 to December 2019. A convenience sample was selected, and their medical records were reviewed. Sociodemographic, imaging and clinical data are presented as results in a database of the vascular surgery and angiology service. Results: 87 patients were evaluated, with an average age of 70 years ± 11 years. The technique was endovascular in 48 patients and an open technique in 37 patients. Among the most frequent complications were the need for amputation 20. 6% and wound infection 18. 3%. The factors associated with complications were the presence of DM, greater severity of the disease and a history of AMI. Conclusions: The data analysis showed similar outcomes in the management with both techniques. The rate of amputation and infection of the operative site did not differ between the types of management performed. A significant association was evidenced in patients with diabetes and / or 3 or more comorbidities with death.
