Is the left middle cerebral artery occluded severely?

The left middle cerebral artery is severely occluded. The left middle cerebral artery supplies blood to the left hemisphere and is a very important artery. It branches from the internal carotid artery and enters the skull. After entering the skull, its terminal artery is the middle cerebral artery. The occlusion of the middle cerebral artery is due to the presence of risk factors for cerebral atherosclerosis, such as hypertension, hyperglycemia, and even atrial fibrillation. If the middle cerebral artery is occluded, brain MRA or CTA or DSA should be performed to confirm the diagnosis. This kind of situation may not show movement disorder, weakness and paralysis of the contralateral limb, indicating that the vascular compensation is relatively good, and it is necessary to strictly control the atherosclerotic factors to make the blood vessels fully compensated, so as not to show poor blood supply or even infarction.
