[The primitive otic artery, a very rare, persistent, primitive artery (author's transl)].
A very rare carotid-basilar anastomosis, the primitive otic artery, is described. In the presence of hypoplasia of the vertebral and basilar arteries and dorsal interruption of the circle of Willis, an attempt is made to explain the situation embryologically and to discuss the disadvantages associated with this condition.
