Peritonitis as presentation of aorto-caval fistula with Salmonella choleraesuis-associated abdominal aortic aneurysm

Abstract

The majority of aorto-caval fistulae occur spontaneously, either as a result of rupture of an existing atherosclerotic abdominal aortic aneurysm into the vena cava or secondary to iatrogenic injuries during peripheral angiography or surgery. Aorto-caval fistula from an infected aortic aneurysm is a rare scenario, but potentially lethal. Case report and review of the literature. A 63-year-old female with diabetes mellitus and liver cirrhosis was admitted for intractable abdominal pain with rebound tenderness. A computed tomography scan demonstrated an abdominal aortic aneurysm and ill-defined peri-aortic fluid with air density and evidence of a fistula between the aorta and the inferior vena cava. Salmonella cholerasuis had been isolated from a blood culture at a previous admission. Urgent endovascular exclusion of the aorto-caval fistula was carried out, and the infra-renal abdominal aneurysm was repaired using a Cook Zenith TX2 aortic stent graft. She received parenteral ceftriaxone for four weeks. This case shows acceptable short-term results after endovascular repair of a Salmonella-infected aorto-caval fistula.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
