Background
Malnutrition is known as a prognostic factor in patients with chronic limb-threatening ischemia (CLTI). However, its impact in CLTI patients with isolated below-the-knee (BTK) lesions who underwent endovascular therapy (EVT) remains unclear. We aimed to investigate the prognostic significance of nutritional status assessed by the controlling nutritional status (CONUT) score in this population.
Methods
We retrospectively analyzed CLTI patients with isolated BTK lesions who underwent EVT. Patients were stratified into four groups according to the CONUT score (0-1, 2-4, 5-8, 9-12, reflecting normal, mild, moderate, and severe malnutrition, respectively). The primary endpoint was amputation-free survival (AFS). And we also evaluated bleeding events.
Results
A total of 233 patients were included. During the median follow-up period was 390 days, the AFS rates were 89.3% in patients with a CONUT score of 0–1 (normal nutrition), 76.8% in those with 2–4 (mild malnutrition), 75.2% in those with 5–8 (moderate malnutrition), and 66.7% in those with 9–12 (severe malnutrition). Severe malnutrition status was significantly associated with worse AFS compared with other nutritional groups (log-rank p<0.001). Furthermore, bleeding events were significantly more frequent in patients with severe malnutrition group (log-rank p<0.001).
Conclusion
Nutritional status assessed by the CONUT score is a strong prognostic indicator in CLTI patients with isolated BTK lesions undergoing EVT. Severe malnutrition was associated with both impaired limb-related outcomes and higher bleeding risk, underscoring the importance of nutritional assessment in this high-risk cohort.
