28 lis 2022 · The deep dorsal metacarpal veins lead to the formation of the primary venous drainage structure of the hand, the dorsal venous network. The dorsal venous network is formed just superficial to the dorsal metacarpus and receives venous blood from the dorsal metacarpal veins, along with dorsal digital veins of the first and fourth digits.
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.
