I65. 02 - Occlusion and stenosis of left vertebral artery. ICD-10-CM.
Vertebral artery stenosis (also called vertebrobasilar insufficiency) happens when the vertebral and basilar arteries at the base of the brain become blocked. These arteries supply blood to the brainstem and the cerebellum.
A cerebral infarction is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). It is caused by disrupted blood supply (ischemia) and restricted oxygen supply (hypoxia), most commonly due to thromboembolism, and manifests clinically as ischemic stroke.
Occlusion or impairment of the vertebrobasilar blood supply affects the medulla, cerebellum, pons, midbrain, thalamus and occipital cortex. This results in a number of clinical syndromes and is caused primarily by atherosclerosis.
The vertebral arteries divide into four segments based on where they are within the spinal column: V1 (pre-foraminal) arises from the subclavian artery. It runs behind the carotid artery, which is also in the neck.
The RMA has defined "precerebral artery" as meaning "extracerebral arteries supplying the brain, including the carotid artery, vertebral artery, basilar artery and ascending aorta".
Obstruction in blood flow (ischemia) to the brain can lead to permanent damage. This is called a cerebrovascular accident (CVA). It is also known as cerebral infarction or stroke. Rupture of an artery with bleeding into the brain (hemorrhage) is called a CVA, too.
The term ischemia means that blood flow to a tissue has decreased, which results in hypoxia, or insufficient oxygen in that tissue, whereas infarction goes one step further and means that blood flow has been completely cut off, resulting in necrosis, or cellular death.
Cerebral infarction is one of the complications of neoplasm. Several factors could induce ischemic stroke in patients with neoplasm. For example, occlusion of the cerebral artery due to compression by head and neck tumors could cause ischemic stroke.
Over time, as plaque continues to build up on your vertebral artery walls, the vessels can become so congested that blood has a hard time passing through them. This is a condition called vertebral artery stenosis, also known more broadly as vertebrobasilar disease or vertebrobasilar insufficiency.
If the resulting loss of brain function is permanent, it' s called a stroke (an infarction or brain attack). A stroke can either be caused by blockage in the vertebral or basilar artery or the breaking off of a piece of plaque (embolus) that travels downstream and blocks a portion of the blood flow to the brain.
Conclusions— Contrast-enhanced MR angiography is the most sensitive noninvasive technique to detect vertebral artery stenosis and also has high specificity. CT angiography has good sensitivity and high specificity. In contrast, ultrasound has low sensitivity and will miss many vertebral stenoses.
