Key points
- A novel congenital portosystemic shunt variant was discovered via cadaveric dissection.
- The shunt involves a direct connection between the left gastroepiploic vein and the left renal vein.
- This anatomical variation allows portal blood to bypass the liver's filtration system.
- The individual's portal venous system and liver showed no signs of disease (fibrosis or hypertension).

Abstract
Congenital portosystemic shunts are rare developmental anomalies that permit portal blood to bypass hepatic filtration. We describe a novel gastrorenal shunt identified during routine cadaveric dissection. A large aberrant vein connecting the left renal vein directly to the left gastroepiploic vein, forming an unusual connection between the systemic and portal circulations. The portal venous system was otherwise intact, with no evidence of hepatic fibrosis or portal hypertension. This configuration does not conform to previously reported portosystemic shunt malformation patterns and is most consistent with a previously unreported variant of a Type II congenital extrahepatic portosystemic shunt.
