Summary
A spontaneous aortocaval fistula (ACF) from a ruptured aortic aneurysm was diagnosed using computed tomography (CT). This case offers the first CT-pathologic correlation for ACF, enhancing diagnostic accuracy.
Area of Science:
- Vascular Surgery
- Radiology
- Pathology
Background:
- Aortocaval fistula (ACF) is a rare complication.
- Spontaneous rupture of atherosclerotic infrarenal aortic aneurysms is a known, though infrequent, cause.
Observation:
- A case of ACF secondary to spontaneous rupture of an infrarenal aortic aneurysm into the inferior vena cava.
- Initial diagnosis was made using computed tomography (CT).
Findings:
- This report provides the first CT demonstration of the exact fistula site.
- CT findings were correlated with pathologic data.
- Retrospective review of two additional ACF cases and literature was performed.
Implications:
- CT imaging is crucial for diagnosing ACF and identifying the precise fistula location.
- CT-pathologic correlation improves understanding of ACF etiology and presentation.
- Enhanced diagnostic capabilities can guide surgical or endovascular management.
