Remote History of Salmonella Bacteremia Resulting in Primary Aorto-duodenal Fistula

Q: What is the clinical evidence from this study?

Study design: Case Report. Population: Primary aorto-duodenal fistula and ruptured saccular infrarenal abdominal aortic aneurysm (n=1). Intervention: Prior Salmonella bacteremia / Surgical repair (extra-anatomic bypass, infected endograft explantation, and duodenojejunostomy).

Q: What does this research mean for the field?

Key result

Prior Salmonella bacteremia leads to aorto-duodenal fistula requiring extra-anatomic bypass and endograft explantation.

n=1

Why the study?

Primary aortoenteric fistula (PAEF) is a rare, life-threatening communication between the aorta and bowel that presents diagnostic challenges and a possible association with prior Salmonella infection.

Key Points

To describe the diagnosis and surgical management of a primary aortoenteric fistula arising in a patient with a remote history of Salmonella bacteremia and emphysematous aortitis.
Assessed a 69-year-old man presenting with CT findings suggestive of pseudoaneurysms and a history of Salmonella-associated emphysematous aortitis.
Performed diagnostic workup using repeat CT, upper endoscopy, and a percutaneous catheter contrast study after initial endovascular repair.
Operative findings revealed a ruptured saccular infrarenal abdominal aortic aneurysm treated initially with endovascular stent placement.
A percutaneous catheter contrast study successfully confirmed aorto-duodenal communication following a nondiagnostic endoscopy.
Definitive treatment was achieved through infected endograft explantation, extra-anatomic bypass, and duodenojejunostomy.

Exposure

Initial endovascular repair, followed by definitive management with extra-anatomic bypass, infected endograft explantation, and duodenojejunostomy.

This case report highlights the diagnostic challenges of primary aorto-duodenal fistula and suggests a possible association with prior Salmonella bacteremia and emphysematous aortitis.

Warrants inclusion of aortoenteric fistula in the differential after Salmonella aortitis; leaves open standardized diagnostic and management protocols.

Abstract

Primary aortoenteric fistula (PAEF) is a rare, life-threatening communication between the aorta and bowel. We report a 69-year-old man with stable emphysematous aortitis from prior Salmonella bacteremia who presented with CT findings concerning for pseudoaneurysms requiring endovascular repair, with intra-operative findings of ruptured saccular infrarenal abdominal aortic aneurysm. Postoperatively, CT demonstrated a complex peri-aortic collection, and percutaneous catheter contrast study confirmed communication with the duodenum after nondiagnostic endoscopy. Definitive management included extra-anatomic bypass, infected endograft explantation, and duodenojejunostomy. This case highlights diagnostic challenges and a possible association with prior Salmonella infection.

Kostara et al. (2026) conducted a case report in Primary aorto-duodenal fistula and ruptured saccular infrarenal abdominal aortic aneurysm (n=1). Prior Salmonella bacteremia / Surgical repair (extra-anatomic bypass, infected endograft explantation, and duodenojejunostomy) was evaluated. Prior Salmonella bacteremia in a 69-year-old man led to a primary aorto-duodenal fistula managed by extra-anatomic bypass, endograft explantation, and duodenojejunostomy.
