Endosvascular Treatment of Mycotic Thoracic Aortic Pseudoaneurysm Secondary to Nontyphoidal Salmonella Infection

Abstract

Abstract Treatment of patients with infected aortic aneurysm remains a challenge for the vascular surgeon and carries a high risk of mortality. Here, we present a case of a patient with infected thoracic aneurysm treated successfully with endovascular technique. The female patient, age 57 years, was admitted to the hospital due to severe thoracic pain. The angiotomography revealed inflammation of the thoracic aorta along with the presence of air bubbles. Stool and blood cultures were positive for Salmonella ser. Enteritidis. Targeted antibiotics were given intravenously for 22 days followed by oral delivery for 6 months. After 14 weeks, angiotomography showed the presence of pseudoaneurysm of the descending thoracic aorta with a diameter of 87 mm, and a thoracic stent-graft was implanted. No endoleaks were detected at the 3-year follow-up. The presented patient with Salmonella-positive infected thoracic aneurysm was successfully treated with endovascular method but still needs lifelong follow-up.
