Summary
This case report details a rare instance of Salmonella infection causing aortoduodenal fistula, a serious complication of aortic pseudoaneurysm. Prompt surgical intervention led to an uncomplicated recovery, highlighting the importance of timely diagnosis and treatment for this condition.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Gastroenterology
Background:
- Primary aortoenteric fistula typically results from abdominal aortic aneurysm erosion into the bowel.
- Septic aortitis leading to pseudoaneurysm and subsequent fistula formation is an exceptionally rare etiology.
- Salmonella-induced aortitis presenting as an aortoduodenal fistula is exceedingly uncommon in medical literature.
Observation:
- A 51-year-old male presented with sepsis secondary to Salmonella bacteremia.
- Imaging revealed an infrarenal aortic pseudoaneurysm.
- Emergency laparotomy identified a fistula between the duodenum and a pseudoaneurysm of a severely infected aorta.
Findings:
- Surgical excision of the infected aortic segment and repair of the duodenal defect were performed.
- Aortic stumps were sutured, and an axillobifemoral bypass was established.
- The patient experienced an uncomplicated postoperative recovery.
Implications:
- This case underscores the potential for Salmonella aortitis to cause aortoduodenal fistulas.
- Highlights the critical role of prompt diagnosis and aggressive surgical management in improving patient outcomes.
- Contributes rare insights into the management of infectious aortoenteric fistulas.

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
01:15Aortic Regurgitation I: Introduction
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
