Prognostic value of the systemic immune-inflammation index in acute limb ischemia undergoing endovascular therapy
Background Acute limb ischemia (ALI) is a vascular emergency associated with major amputation and mortality, highlighting the need for early risk stratification. The systemic immune-inflammation index (SII), calculated from platelet, neutrophil, and lymphocyte counts, is a composite biomarker reflecting systemic inflam...
