The dorsal venous network of the hand is a venous network on the dorsum (backside) of hand. It is formed by the dorsal metacarpal veins (three in number), a dorsal digital vein from the radial (lateral) side of the index finger and one from the ulnar (medial) side of the little finger, and both dorsal digital veins of the thumb.

Dec 1, 2021 · In recent years, dorsal hand vein (DHV) recognition, as an emerging biometrics technology, has received much attention. It is well known that DHV recognition belongs to the family of hand-based biometrics.

Dec 2, 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 longitudinal dorsal veins of the fingers and thumb run together proximal to the MCP joints by converging at the interdigital web spaces and are formed by oblique veins from the palmar venous system (Figures 1A and 2A and 2B).

It is well known that the most common sites for venous access are the superficial veins of the upper limb, particularly dorsal metacarpal veins and median cubital vein. Although dorsal metacarpal veins are the first choice for venous cannulation, ...

Explore the intricate dorsal venous network of the hand, its origin, course, tributaries, and drainage system.

The dorsal hand veins are part of the superficial venous network of the hand. The dorsal hand veins drain blood from the dorsal side of the hand to the larger basilic, accessory cephalic, and cephalic veins in the forearm.

Dec 8, 2021 · Venous drainage of the hand is predominantly via the dorsal venous network in the superficial fascia, which extends proximally across the dorsal aspect of the metacarpus to drain laterally into the cephalic vein, and medially into the basilic vein 1.

A network of veins in the superficial fascia of the dorsum of the hand (back of the hand), formed by the dorsal metacarpal veins gives the origin of the basilic vein and the cephalic vein.

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 …
