Aortoduodenal Fistula Definition An aortoduodenal fistula is a rare and potentially life-threatening condition where there is an abnormal connection between the aorta and the duodenum, allowing blood to flow directly from the aorta into the duodenum. Causes 1. Aortic aneurysm or pseudoaneurysm 2. Aortic graft infection or erosion 3. Duodenal ulcer or cancer 4. Trauma (e.g., gunshot wound) 5. Infection (e.g., endocarditis, tuberculosis) 6. Congenital anomaly Symptoms 1. Gastrointestinal bleeding (e.g., hematemesis, melena) 2. Abdominal pain 3. Weight loss 4. Fever 5. Chills 6. Nausea and vomiting Diagnosis 1. Endoscopy (e.g., upper GI endoscopy) 2. Imaging studies: CT angiography MRI angiography Ultrasound 3. Angiography 4. Blood tests (e.g., complete blood count, electrolytes) Classification 1. Primary aortoduodenal fistula: direct connection between aorta and duodenum 2. Secondary aortoduodenal fistula: connection through an intervening structure (e.g., graft, pseudoaneurysm) Treatment 1. Surgical repair: Aortic graft replacement Duodenal repair or resection Fistula closure 2. Endovascular repair: Stent graft placement Embolization 3. Medical management: Antibiotics Blood transfusions Fluid resuscitation Complications 1. Severe bleeding 2. Hemorrhagic shock 3. Sepsis 4. Multi-organ failure 5. Death #Fistula
