Medical Intelligence & Overview
Dissection of other precerebral arteries, including the basilar artery, is a type of vascular injury that occurs when there is a tear in the inner layer of these blood vessels. This tear can cause blood to enter the vessel wall, leading to a separation of the layers (dissection). Such dissection can disrupt blood flow to the brain, potentially resulting in serious neurological issues. This condition is classified under the ICD-10 code I77.75 and involves arteries that are responsible for supplying blood to the brain before they reach the brain tissue itself.
