Arterial steal blood: Carotid steal blood syndrome refers to the occlusion of the internal carotid artery on one side, the healthy internal carotid artery blood flow through the anterior communicating artery into the affected side, the healthy internal carotid artery blood flow through the anterior communicating artery into the affected side, the healthy internal carotid artery system ischemic performance, or the vertebrobasilar artery blood flow can be reversed through the posterior communicating artery into the affected internal carotid artery, resulting in the vertebrobasilar artery system ischemic performance, such as bilateral internal carotid artery If both internal carotid arteries are occluded, the vertebrobasilar artery and external carotid artery can compensate for the blood supply, and the brain and cerebellum can be damaged at the same time. The cause is mostly the formation of atherosclerotic sections. Clinical manifestations include recurrent episodes of transient cerebral arterial insufficiency in the internal carotid system, such as transient black clouding on the side of the lesion, numbness of the limb opposite the lesion, mild hemiparesis, aphasia, etc. With internal carotid artery stenosis >75%, a vascular murmur can be heard and the internal carotid pulse is diminished or hourly. When there are symptoms of ischemia in a vascular supply area and DSA is normal, cerebral artery reflux or blood theft syndrome should be considered as a possibility. What should be the diet of arterial blood steal? 1, lean meat: belongs to the food rich in protein, which is very beneficial to the body and can supplement high-quality protein. 2, fruit: rich in vitamin content makes it popular, the most popular fruit. 3, eggs: rich in high-quality protein and essential vitamins, belong to the high-calorie food.
