Overview

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.

Causes

Life Threatening Causes

Common Causes

The most common causes of VBI are cardioembolism, atherosclerosis, and small artery disease.[1]
