Vertebrobasilar insufficiency causes
Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]
Overview
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
Causes
Life Threatening Causes
- Vertebrobasilar aneurysm
- Stroke caused by arterial embolism
- Subarachnoid hemorrhage caused by vertebral artery dissection
Common Causes
The most common causes of VBI are cardioembolism, atherosclerosis, and small artery disease.[1]
