  • lateral
  • It runs backward and upward on the lateral wall of the pelvis below the obturator artery, and then passes between the ureter and the hypogastric artery, to end in the hypogastric vein. (wikipedia.org)
  • In anatomy, the radial veins are venae comitantes that accompany the radial artery through the back of the hand and the lateral aspect of the forearm. (wikipedia.org)
  • 2) four lateral longitudinal veins which run behind the nerve roots. (wikipedia.org)
  • The choroid veins are the superior choroid vein and the inferior choroid vein of the lateral ventricle. (wikipedia.org)
  • The superior choroid vein runs along the length of the choroid plexus in the lateral ventricle. (wikipedia.org)
  • insufficiency
  • Varicose veins are predominately seen in the lower extremities and are a manifestation of chronic venous valvular insufficiency causing increased pressure in the lower extremity venous system. (springer.com)
  • Restless legs syndrome appears to be a common overlapping clinical syndrome in people with varicose veins and other chronic venous insufficiency. (wikipedia.org)
  • Clinical test that may be used include: Trendelenburg test-to determine the site of venous reflux and the nature of the saphenofemoral junction Traditionally, varicose veins were investigated using imaging techniques only if there was a suspicion of deep venous insufficiency, if they were recurrent, or if they involved the saphenopopliteal junction.

  • valves
  • Hepatic veins are unusual in that they do not have valves. (innerbody.com)
  • To do their job, veins are full of valves that help keep the blood flowing in the right direction. (kidshealth.org)
  • To ease this process, the veins have little valves that snap shut behind the blood as it travels upwards. (everything2.com)
  • Should any of these valves wear out, blood collects in the veins making them bulge , giving a very attractive lumpy-leg feature. (everything2.com)
  • With such notable exceptions as the portal system, most veins contain valves, formed by pouches in their inner coats, that keep the blood from flowing backward. (infoplease.com)
  • Valves are most numerous in the veins of the extremities, and are absent in the smallest veins. (infoplease.com)
  • When they are functioning normally, these valves prevent blood from flowing back away from the heart, but if their efficiency decreases some blood may stagnate in the vein, which then becomes swollen and twisted, causing aching and abnormal fatigue of the legs. (healthy.net)
  • Veins have pairs of leaflet valves to prevent blood from flowing backwards (retrograde flow or venous reflux). (wikipedia.org)
  • When veins become varicose, the leaflets of the valves no longer meet properly, and the valves do not work (valvular incompetence). (wikipedia.org)
  • None of the hepatic veins have valves. (wikipedia.org)
  • clinical
  • Randomized clinical trial comparing endovenous laser ablation, radiofrequency ablation, foam sclerotherapy, and surgical stripping for great saphenous varicose veins with 3-year follow-up. (springer.com)
  • Typically, the entrances to the vortex veins in the outer layer of the choroid (lamina vasculosa) can be observed funduscopically and provide an important clinical landmarks identifying the ocular equator. (wikipedia.org)
  • outer
  • their outer coat consists of fibrous tissue, their inner of an endothelial layer continuous with the lining membrane of the veins. (theodora.com)
  • swollen
  • It's a vein that has become stretched and swollen with blood. (kidshealth.org)
  • The extra weight increases the pressure on the veins which causes them to become weakened and swollen, thereby restricting the blood supply towards the heart. (medic8.com)
