Historical Perspective

The concept of “vertebrobasilar insufficiency" was first described in 1961 by Niedermeyer.

Classification

There isn't classification about the VBI yet, but there are three phenotypes of the basilar artery occlusion depending on the modal of initial symptoms.

Causes

The causes leading to VBI is primarily the vasulcar ones, like atherosclerosis and cardioembolism, etc. As the vertebral artery is in the cervical vertebra, the orthopedical lesion also contribute to part of the causes.
