[Aneurism in a persisting sciatic artery. One case (author's transl)]

The authors report on the first case of aneurism in a persisting sciatic artery observed in France. The condition was complicated by truncular embolism and fissuration and was successfully treated by endo-aneurismorrhaphy. Restoration of arterial continuity is nevertheless necessary in most cases of aneurysm affecting a complete persistant sciatic artery (providing the vascular supply for the whole lower limb) which represents the commonest anatomical type.
