[Communicating (perforating) veins of the hand]

With the aim to study the problem whether there are at the hand and wrist communicating veins which are constant, we made 25 anatomical dissections. The results showed that five groups may be distinguished, viz. distal and proximal interosseous communicating veins, and dorsal, radial and ulnar carpal communicating veins. Among the veins of these groups there are a number of 4 which are constant, and a number of 5 which are nearly constant.
