Figure 2d. (a) Drawing illustrates potential draining veins. AZV = azygos vein, ICV = intercostal vein, IPV = inferior phrenic vein, LRV = left renal vein, PEV = paraesophageal vein, PPhV = pericardiophrenic vein, VPlx = vertebral venous plexus. (b) Magnetic resonance angiogram shows fundal gastric varices (GV) draining through the gastrorenal (arrowheads) and gastrocaval (single arrows) shunts into the inferior vena cava (double arrows). LGV = left gastric vein, RV = renal vein. (c) Balloon-occluded venogram shows that the inferior phrenic vein (gastrorenal shunt) communicates with the pericardiophrenic vein (PPhV), an intercostal vein (ICV), and small mediastinal veins. (d) Balloon-occluded venogram shows that the inferior phrenic vein (gastrorenal shunt) is contiguous with the paravertebral plexus (arrows) and azygos vein (AZV).
