Revascularization impact: quality of life enhancement in chronic limb-threatening ischemia

Introduction. Globally, over 230 million people have peripheral artery disease, often undiagnosed, leading to chronic limb-threatening ischemia. Revascularization is vital for preventing amputation and improving quality of life. While specific questionnaires for severe ischemia are lacking, the SF-36 questionnaire is widely used to assess quality of life, with variations like SF-12 and SF-8 for larger cohorts. Objectives. Our aim was to assess how different lower limb revascularization methods affect the postoperative quality of life in patients with chronic limb-threatening ischemia. Methods. This study was conducted at the St. Pantelimon Emergency Hospital of Bucharest, Romania. It included 166 adult patients with chronic limb-threatening ischemia who were monitored for 12 months. Quality of life was assessed using the SF-36 questionnaire. The patients were categorized into two groups: 112 underwent conventional surgery, and 54 had hybrid procedures. Data analysis involved t-tests, Mann-Whitney U tests and assessment of data reliability. Results. In the Conventional Surgery group, the average age was 70.5 years, predominantly male, with similar risk factors as the second group. The Hybrid Surgery group had an average age of 73 and exhibited more extensive distal arterial lesions, higher rates of ulcer/gangrene, and a higher occurrence of postoperative minor amputations. The SF-36 questionnaire showed low data reliability for the General Health and Social Functioning domains. Additionally, the Hybrid Surgery group had poorer preoperative perception in the Body Pain category. However, significant postoperative improvements in quality of life were observed in all domains for both groups with similar results. Conclusions. Revascularization improves the quality of life for patients with chronic limb-threatening ischemia, including those that also require minor amputations. SF-36 has good assessment for most QoL aspects, but reliability declines in severe ischemia.
