[The origin of the arteria sigmoidea ima].
The authors report the results of their observations on the lowest sigmoid artery, carried out on 92 anatomical specimens coming from surgical operations on the sigmoid and rectum. The specimens were injected and radiographed immediately after their removal . The observations were often preceded by pre-operative angiographies performed for diagnostic reasons. The AA. document all the variational patterns of this artery. They confirm the poor functional value of this artery more known by the old surgeons than by the anatomists.
