Abstract

A cerebral large vessel occlusion due to septic embolism with resultant stroke is a known complication of infective endocarditis and can cause severe neurologic disability. However, septic embolism rarely occurs in the absence of infective endocarditis, and emboli due to different organisms may behave differently. As such, it is important to recognize the different pathogens that can cause septic embolism resulting in cerebral large vessel occlusion and to have data on successful treatments. We describe here a case of mechanical thrombectomy for septic embolism secondary to Staphylococcus lugdunensis bacteremia without infective endocarditis.

AP road map (B) demonstrates deployment of the EMBOTRAP (Cerenovus, Miami, FL, USA) across the embolus. An AP view angiogram (C) demonstrates modified thrombolysis-in-cerebral-infarction 2C reperfusion after embolectomy. H&E stains under 5× (D) and 20× (E) magnification demonstrate an embolism with bacterial colonization (blue arrows).
