Figure 6.

Efferents (hepatofugal) from duodenal varices. The efferent from DV can be hepatopetal or hepatofugal. The figure shows hepatofugal pathways from the duodenal varices which can go to following tributaries. 1. Right renal vein (mesentero renal shunt)* 2. gonadal vein (mesentero gonadal shunt)* 3. lumbar veins 4. iliac vein* 5. IVC = inferior vena cava, 6. right suprarenal vein 7. right inferior phrenic vein 8. Ascending lumbar vein 9. Right subcostal vein 10. Azygos vein 11. Tributary of right renal vein–right inferior adrenal vein*. The veins marked by stars (*) have been demonstrated to act as hepatofugal collaterals of duodenal varices.
