A Rare and Interesting Presentation of Diabetic Ketoacidosis Caused by Native Aortic Valve Endocarditis Complicated by Aortic Root Abscess Resulting in Multiple Septic Emboli Causing Bowel Ischemia and Splenic Infarction

Abstract

Diabetic ketoacidosis (DKA) is a serious life-threatening complication of diabetes, often precipitated by infection. Infective endocarditis (IE) is a serious precipitating factor for DKA, especially in patients with a previous cardiac surgery or valvular pathology. IE can be further complicated by life-threatening embolic events, which could be fatal if not detected and managed early and effectively. Our patient is a 54-year-old diabetic who presented with DKA precipitated by native aortic valve endocarditis complicated by an aortic root abscess, which was further complicated by septic emboli to the splenic artery and superior mesenteric artery leading to splenic infarction and bowel ischemia, respectively. To our knowledge and as per the literature reviewed, no case has been reported in a single patient who presented with DKA precipitated by IE complicated by aortic root abscess and multiple septic emboli resulting in bowel ischemia and splenic infarction.
