Insights
This study reports a rare case of multiple congenital vascular anomalies in the celiac axis, portal vein, and hepatic veins. A unique arteriovenous fistula between the hepatic artery and a hepatic vein was identified.
Area of Science:
- Vascular Surgery
- Congenital Abnormalities
- Radiology
Background:
- Vascular anomalies present diagnostic and therapeutic challenges.
- Congenital vascular malformations require precise anatomical understanding.
Observation:
- A patient exhibited multiple vascular anomalies affecting the celiac axis and portal venous system.
- The case presented a large arteriovenous fistula connecting the hepatic artery directly to a hepatic vein.
Findings:
- The observed vascular anomalies, including the arteriovenous fistula, are presumed to be congenital.
- This specific combination of anomalies, particularly the hepatic arteriovenous fistula, appears unique in existing literature.
Implications:
- This case highlights the importance of comprehensive vascular imaging for diagnosing complex congenital anomalies.
- Understanding such rare presentations can inform surgical planning and patient management for similar vascular malformations.
Abstract:
A patient is presented with multiple vascular anomalies in the branches of the celiac axis as well as in the portal vein and its branches. Apparently, unique in the literature is the presence of a large arteriovenous fistula between the hepatic artery and one of the hepatic veins. The anomalies are presumed to be congenital in origin.
