Primary aortoduodenal fistula: a rare entity with lethal effects

Area of Science:

• Gastroenterology
• Vascular Surgery
• Diagnostic Imaging

Background:

• Primary aortoduodenal fistula (ADF) is an uncommon yet severe condition.
• It involves an abnormal connection between the aorta and the duodenum.
• ADF often presents with high morbidity and mortality rates.

Observation:

• A case of a patient with primary ADF is presented.
• The patient experienced mortality due to the condition.
• Diagnostic efforts, including radiographic and endoscopic imaging, were repeatedly unsuccessful in identifying the fistula.

Findings:

• The fistula remained undetected until the patient experienced fatal exsanguination.
• Diagnostic modalities for ADF have limitations.
• A high index of suspicion is crucial for timely diagnosis.

Implications:

• This case underscores the diagnostic difficulties associated with primary ADF.
• The findings emphasize the need for heightened clinical awareness in suspected cases.
• Improved diagnostic strategies or earlier recognition may improve patient outcomes for this rare condition.
