The arteriovenous pattern of the distal digital segment.

By injection of eosin dye with latex into 45 cadaveric fingers we were able to demonstrate: (1) a distinct digital pulp arch formed by the ulnar and radial digital arteries over the mid-point of the terminal phalanx in 93% of digits; (2) variations in size of the proper digital arteries to each digit; (3) numerous branches from the pulp arch to the tip of each digit and (4) a constant pattern of dorsal veins over the terminal segment in 89% of digits.
