Surgical treatment of a -related infective native aortic aneurysm: A case report

Abstract

Infective native abdominal aortic aneurysms are a life-threatening condition with a high mortality rate. We report the case of a 53-year-old male patient who presented with abdominal pain and fever. Laboratory results showed an elevated white blood cell count and C-reactive protein levels. Blood cultures detected Salmonella species, and computed tomography revealed a saccular abdominal aortic aneurysm. After 14 days of preoperative antibiotic therapy, the patient underwent a successful surgical bypass from the descending thoracic aorta, through the diaphragm and muscle layers of the anterior abdominal wall, to the bilateral common femoral arteries. The patient was discharged after 30 days of hospitalization and continued antibiotic treatment for another 30 days. Follow-up clinical evaluations and imaging studies showed good recovery and no signs of infection. This case highlights the importance of combining appropriate antibiotic therapy with surgical intervention in managing infective native aortic aneurysms. In particular, an extra-anatomical approach from the descending aorta can be a viable option in selected cases of infected aortic aneurysms, providing an effective means to achieve thorough debridement and prevent future graft infections.
