[Anatomical organization, organogenesis and innervation of the arteries of the hand].

The authors sum up the anatomical aspects of the arteries of the hand. They emphasise the fact that, by the side of the classical description; there is a lot of variations. These can be explained by organogenesis, showing that hand arteries pass over several stages, before reaching the terminal one. Generally, it seems that the classical diagram correspond to the majority of cases, and that there is a main flow for hand's arteries: this are the superficial and deep arches, which give common and proper digital arteries. About the innervation, this structures are very richly innervated, but this sympathetic innervation is not so precisely delimited in its topography, and for that reason, its seems to be difficult to give an clear diagram of its origin and distribution. That can explain surgical treatment's failure in vasomotor syndromes of upper limbs.
