| systemic venous hypertension | Increased pressure in the veins ultimately leading to the right atrium nearly always due to disease of the right heart but occasionally due to blockade of one or both venae cavae. (05 Mar 2000) |
|---|---|
| dorsal venous arch of foot | The arch in the subcutaneous tissue of the dorsum of the foot formed by the dorsal and digital veins; it unites medially with the dorsal vein of the great toe to form the great saphenous vein, and laterally with the dorsal vein of the little toe to form the small saphenous. Synonym: arcus venosus dorsalis pedis. (05 Mar 2000) |
| 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) |
| 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) |
| abdominal fissure | Congenital failure of the ventral body wall to close. See: celosomia, gastroschisis. (05 Mar 2000) |
| Ammon's fissure | A pearl-shaped opening in the sclera during early embryogenesis. (05 Mar 2000) |
| anal fissure | A tear or superficial laceration that can occur in the mucosa that lines the anal canal. (27 Sep 1997) |
| anterior median fissure of medulla oblongata | The longitudinal groove in the midline of the anterior aspect of the medulla oblongata; it is the medullary equivalent of the anterior median fissure of the spinal cord and ends at the foramen caecum posterius; its caudal part is obliterated by the decussation of the pyramids. Synonym: fissura mediana anterior medullae oblongatae, anteromedian groove. (05 Mar 2000) |
