22 lip 2014 · The deep veins of the lower extremity consist of axial veins, which follow the course of the major arteries, and intramuscular veins, including venous sinusoids and plexi. The perforating veins traverse the anatomic fascial layer to connect the superficial to the deep venous system.
The lower extremity venous network consists of deep and superficial veins connected by perforators and contains intraluminal valves that help ensure unidirectional blood flow toward the heart. The largest axial superficial veins of the lower extremities include the great saphenous vein (GSV) and the small saphenous vein (SSV).
The deep veins of the lower extremities primarily drain muscles and are encompassed by muscular fascia. The veins located between the skin and the muscular fascia are considered superficial veins. Superficial veins drain the cutaneous microcirculation.
30 wrz 2006 · Venous return from the dependent lower extremity is achieved by the ejection of blood by the lower extremity muscle pumps, assisted by competent venous valves.
1 cze 2014 · The deep veins of the lower extremities accompany arteries, primarily drain muscles, and are encompassed by muscular fascia. The veins located between the skin and the muscular fascia are considered superficial veins.
Anatomy. Venous blood from the lower limbs returns to the right heart against gravity through the superficial and deep venous systems.
