| venae occipitales | The superior cerebral veins draining the occipital cortex and emptying into the superior sagittal sinus and the transverse sinus. Synonym: venae occipitales. (05 Mar 2000) |
| venae oesophageae | Series of veins draining the submucous venous plexus of the oesophagus; proceding inferiorly from the cervical portion of the oesophagus, they drain to the inferior thyroid vein, the superior intercostal veins, the azygos, accessory hemiazygos and hemiazygos veins, all of which are ultimately tributaries of the superior vena cava; the most inferior oesophageal veins, from the cardiac portion of the oesophagus, drain via the oesophageal branches of the left gastric vein, a tributary of the portal vein. Thus, the submucosal veins of the inferior oesophagus form a portocaval anastomoses, and are subject to the formation of varicosities in portal hypertension. Synonym: venae oesophageae.

| venae palpebrales superiores | Veins draining the superior eyelid anteriorly into the angular vein. Synonym: venae palpebrales superiores, veins of superior eyelid. (05 Mar 2000) |

| venae paraumbilicales | Several small veins arising from cutaneous veins about the umbilicus running along the round ligament of the liver, and terminating as accessory portal veins in the substance of this organ; they constitute a portocaval anastomosis and are subject to varicosity druign portal hypertension; varicose paraumbilical veins form the "caput medussae". Synonym: venae paraumbilicales, Sappey's veins. (05 Mar 2000) |
