[Right subclavian arteria lusoria with anomaly of the origin of the two vertebral arteries. A cause of functional vertebrobasilar insufficiency (author's transl)].

The authors describe 1 case of right subclavian arteria lusoria with anomaly of the origin of both vertebral arteries (aortic on the left and from the primary carotid artery on the right).
