| great cerebral vein of Galen | A large, unpaired vein formed by the junction of the two internal cerebral veins in the caudal part of the tela choroidea of the third ventricle; it passes caudally between the splenium of the corpus callosum and the pineal gland, curving dorsally to merge with the inferior sagittal sinus to form the straight sinus. Synonym: vena cerebri magna, great cerebral vein, great vein of Galen. (05 Mar 2000) |

| great saphenous vein | <anatomy, vein> Formed by the union of the dorsal vein of the great toe and the dorsal venous arch of the foot, ascends in front of the medial malleolus, behind the medial condyle of the femur, and traverses the saphenois hiatus in the fascia lata to empty into the femoral vein in the upper part of the femoral triangle. Synonym: vena saphena magna, large saphenous vein, long saphenous vein. (05 Mar 2000) |
| great vein of Galen | A large, unpaired vein formed by the junction of the two internal cerebral veins in the caudal part of the tela choroidea of the third ventricle; it passes caudally between the splenium of the corpus callosum and the pineal gland, curving dorsally to merge with the inferior sagittal sinus to form the straight sinus. Synonym: vena cerebri magna, great cerebral vein, great vein of Galen. (05 Mar 2000) |
| right branch of portal vein | <anatomy, vein> Terminal branch of hepatic portal vein distributed to right lobe of liver tributary: cystic vein. Synonym: ramus dexter venae portae hepatis. (05 Mar 2000) |

| right gastric vein | <anatomy, vein> It receives veins from both surfaces of the upper portion of the stomach, runs to the right along the lesser curvature of the stomach, and empties into the portal vein. Synonym: vena gastrica dextra, pyloric vein. (05 Mar 2000) |
| right gastroepiploic vein | <anatomy, vein> A tributary of the superior mesenteric vein that parallels the right gastroepiploic artery along the greater curvature of the stomach. Synonym: vena gastro-omentalis dextra, right gastroomental vein. (05 Mar 2000) |
| right gastroomental vein | <anatomy, vein> A tributary of the superior mesenteric vein that parallels the right gastroepiploic artery along the greater curvature of the stomach. Synonym: vena gastro-omentalis dextra, right gastroomental vein. (05 Mar 2000) |
| right inferior pulmonary vein | <anatomy, vein> The vein returning oxygenated blood from the inferior lobe of the right lung to the left atrium. Synonym: vena pulmonalis inferior dextra. (05 Mar 2000) |
| right ovarian vein | <anatomy, vein> Begins as the pampiniform plexus at the hilum of the ovary and opens into the inferior vena cava. Synonym: vena ovarica dextra. (05 Mar 2000) |
| right ovarian vein syndrome | <syndrome> A condition characterised by intermittent abdominal pain due to ureteral compression by the right ovarian vein, occurring with most frequency on the right side, and thought to be due to aberrant crossing of the right ovarian vein over the ureter, generally at the level of the first sacral vertebra; dilation of the ovarian vein during pregnancy and unilateral ptosis of the kidney are thought to be contributing factors leading to intermittent ureteral obstruction and recurring bouts of pain and pyelonephritis.
