| venous angioma | <radiology> Caput medusae, wedge-shaped appearance with its base at the meninges and its apex directed toward the ventricles, prominent medullary vein drains into a markedly enlarged transcortical cerebral vein, angiogram: normal arterial phase without AV shunting (12 Dec 1998) |
| venous angle | The junction of the internal jugular and subclavian veins, toward which converge the external and the anterior jugular and the vertebral veins, the thoracic duct in the left angle and the right lymphatic duct in the right angle. Synonym: Pirogoff's angle. In neuroradiology, the angle of union of the superior thalamostriate vein (vena terminalis) with the internal cerebral vein, usually closely behind the interventricular foramen of Monro.

| venous return c. |
a graphic representation of venous return as a function of atrial pressure; it measures the contributions of peripheral factors that affect the flow of blood from the veins to the heart. Multiple curves generated under varying conditions are combined with similarly obtained cardiac output curves (q.v.) to analyze cardiac regulation.
