Explore the intricate dorsal venous network of the hand, its origin, course, tributaries, and drainage system.
30 wrz 2024 · The dorsal venous network of the hand is a network of superficial veins located on the back (dorsal surface) of the hand. It forms a visible, branching pattern of veins that drains deoxygenated blood from the dorsal aspect of the hand and fingers.
The dorsal digital veins pass along the sides of the fingers and are joined to one another by oblique communicating branches. Those from the adjacent sides of the fingers unite to form three dorsal metacarpal veins which end in a dorsal venous net-work opposite the middle of the metacarpus.
14 maj 2022 · This first-order dorsal venous arch arises from the meeting of the lateroungual veins as well as the laterodigital oblique veins of the fingertip which connect the palmar pulp venous system to the dorsal network.
If we flip the hand around, we can also identify an extensive dorsal venous network on the dorsum of the hand made up of the dorsal metacarpal, dorsal digital, and intercapitular veins. We'll explore each of these venous networks beginning with the veins on the palmar surface of the hand.
28 lis 2022 · Veins of the hand are largely divided into superficial and deep venous systems. Superficial veins of the hand include the dorsal and palmar digital veins and the dorsal venous network. Deep veins of the hand typically follow the arteries of the hand and include the dorsal and palmar metacarpal veins as well as the superficial and deep palmar ...
The dorsal venous plexus (rete venosus dorsale) is located in the area of the wrist and metacarpus of the dorsal surface of the hand. They lie superficially, drain blood from the dorsum of the digital veins and continue from the ulnar side into the basilic vein, and from the ulnar side into the cephalic vein.
