Imminent rupture of abdominal aortic aneurysm complicated by arteriovenous fistulaization and hepatorenal failure: case report and literature review

2020 Reviews in cardiovascular medicine  
Arteriovenous fistula (AVF) is a rare complication of the abdominal aortic aneurysm (AAA) with complex clinical features. However, AVF and AAA usually cause no symptoms except when they rupture. This case study demonstrated that ultrasonography was a rapid and non-invasive method for the initial assessment of AAA and AVF. A 65-year-old man was admitted to the intensive care unit with hepatic and renal dysfunction. Physical examination revealed an abdominal vascular murmur and bilateral toe
