Septic embolism associated with infective endocarditis (IE) is the occlusion of a blood vessel caused by an infected thrombus traveling through the bloodstream resulting in ischemia and/or infarction. Septic embolism can result in ischemia and/or infarction due to vascular occlusion and infection, resulting in inflammation and possible abscess formation. Systemic embolization generally occurs in left-sided IE, causing stroke, blindness due to embolism or endophthalmitis, splenic or renal infarct, limb ischemia, or even acute myocardial infarction. Here, we report a case of acute on chronic limb-threatening ischemia due to septic embolism in patient with IE.
