Quick Facts
Origin: Dorsal metacarpal and dorsal digital veins.
Course: Proximally, extends across the dorsal aspect of metacarpals.
Tributaries: Dorsal digital, intercapitular, and dorsal metacarpal veins.
Drainage: Dorsal aspect of the hand.
Origin
The dorsal venous network of the hand arises from the unification of the dorsal metacarpal and dorsal digital veins.
Course
The dorsal anastomosis forms an asymmetrical dorsal network and, in 70% of individuals, forms a dorsal arch (Tubbs et al., 2016).
Tributaries
The dorsal venous network receives the dorsal digital, dorsal metacarpal, and intercapitular veins. The veins of the dorsal venous network coalesce on the radial aspect with digital veins of the thumb and form the cephalic vein. Conversely, on the ulnar aspect, the network coalesces with the digital veins of the little finger and forms the basilic vein (Doyle and Botte, 2003).
Structures Drained
The superficial venous system is the primary drainage of the hand. The palmar venous drainage is insufficient and blood of the palm of the hand is drained primarily by the dorsal venous network via the intercapitular veins (Doyle and Botte, 2003, Tubbs et al., 2016).
