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.
On the dorsum of the foot the dorsal digital veins receive, in the clefts between the toes, the intercapitular veins from the plantar venous arch and join to form short common digital veins which unite across the distal ends of the metatarsal bones in a dorsal venous arch.
The dorsal digital veins 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. They are a popular site for peripheral venous cannulation because they tend to be prominent veins which are easily accessible and do not lie over a point of ...

The palmar digital veins (or volar digital veins) on each finger are connected to the dorsal digital veins by oblique intercapitular veins. Some sources distinguish between the "proper palmar digital veins", which are more distal, and the "common palmar digital veins", which are more proximal.
Proper palmar digital arteries anastomose freely in the subcutaneous tissue of the finger tips and by smaller branches near the interphalangeal joints. Dorsal branches supplied by the arteries anastomose with the dorsal digital arteries, and supply the soft parts on the back of the second and third phalanges, including the matrix of the fingernail.
Dorsal digital arteries arise from the bifurcation of dorsal metacarpal arteries. They travel along the sides and dorsal aspects of the phalanges of the middle finger, ring finger, and little finger. They communicate with the proper palmar digital arteries. They run with the dorsal digital nerves of ulnar nerve and dorsal digital nerves of ...
