| dorsal venous network of foot | A superficial network of fine veins on the dorsum of the foot. Synonym: rete venosum dorsale pedis. (05 Mar 2000) |
|---|---|
| dorsal venous network of hand | A superficial network of veins on the dorsum of the hand emptying into the cephalic and the basilic veins. Synonym: rete venosum dorsale manus. (05 Mar 2000) |
| dural venous sinuses | Endothelium-lined venous channels in the dura mater. Synonym: sinus durae matris, cerebral sinuses, cranial sinuses, sinuses of dura mater, venous sinuses. (05 Mar 2000) |
| internal carotid venous plexus | A venous network around the internal carotid artery in the carotid canal of the temporal bone, connecting with the cavernous sinus and internal jugular vein. Synonym: plexus venosus caroticus internus, internal carotid (nervous) plexus, plexus caroticus internus. (05 Mar 2000) |
| total anomalous pulmonary venous return | <radiology> (TAPVR) admixture lesion: cyanosis, increased pulmonary blood flow, must have L to R shunt for survival (e.g., atrial septal defect) associated with, atrial septal defect, asplenia (12 Dec 1998) |
| total or partial anomalous pulmonary venous connections | Connections in which some or all of the pulmonary veins connect to the right atrium or one of its tributaries. (05 Mar 2000) |
| jugular venous arch | A connecting vein between the two anterior jugular veins in the suprasternal space. Synonym: arcus venosus juguli. (05 Mar 2000) |
| uterine venous plexus | The plexiform veins that lie along the sides of the uterus in the broad ligament. Synonym: plexus venosus uterinus. (05 Mar 2000) |
| fissure of venous ligament | A deep cleft extending from the porta hepatis and the inferior vena cava between the left lobe and the caudate lobe; it lodges the ligamentum venosum and is thus a vestige of the fossa of the ductus venosus. Synonym: fissura ligamenti venosi, fissure of venous ligament. (05 Mar 2000) |
| lateral venous lacunae | Lateral expansions of the superior sagittal sinus of the dura mater, often increasing in width with advancing age until, in the very old, they may extend two centimeters lateral to the midline; the endothelium-lined lumen of the lacunae are usually reduced to a spongelike labyrinth by numerous arachnoid granulations and dural trabeculae. Synonym: lacunae laterales, lateral lacunae, lateral lakes, parasinoidal sinuses. (05 Mar 2000) |
| accidental murmur | An evanescent cardiac murmur not due to valvular lesion. (05 Mar 2000) |
| anaemic murmur | A nonvalvular murmur heard on auscultation of the heart and large blood vessels in cases of profound anaemia associated mainly with turbulent blood flow due to decreased blood viscosity. (05 Mar 2000) |
| aneurysmal murmur | A systolic or systolic-diastolic murmur heard over some cardiac aneurysms. (05 Mar 2000) |
| aortic murmur | A murmur produced at the aortic orifice, either obstructive or regurgitant. (05 Mar 2000) |
