Escherichia coli‐ Associated Infectious Aortitis Complicated by Abdominal Aortic Aneurysm and Diverticulitis Treated With Covered Endovascular Reconstruction of the Aortic Bifurcation

Infectious aortitis caused by Escherichia coli is exceedingly rare and associated with high mortality. We report a 76‐year‐old man presenting with nonspecific abdominal symptoms and E. coli bacteremia, complicated by an infrarenal eccentric saccular abdominal aortic aneurysm and diverticulitis. The patient was successfully treated with percutaneous endovascular aneurysm repair (PEVAR) using a covered endovascular reconstruction of the aortic bifurcation (CERAB) technique, followed by prolonged targeted antimicrobial therapy. Early contrast‐enhanced imaging and prompt endovascular intervention may prevent catastrophic complications and improve outcomes in high‐risk patients.
