[Anomalous branching of the inferior thyroid artery from the left vertebral artery].

In a 53 years old woman hospitalized for a suddenly developed picture of vascular insufficiency in the verterobrobasillary vascular bed the authors detected an anomalous division of the left vertebral artery from aortic arch. Moreover, at the level of thyroid gland there was the division of inferior thyroid artery from the vertebral artery. We express the opinion that the finding did not participate in the clinical symptomatology.
