Blood flow (tube) spasm occurs in the blood vessels of the brain is both cerebral vasospasm, can also occur in other parts of the body such as coronary arteries.
Vasospasm refers to the stimulation of blood vessels, the smooth muscle of the vessel wall strongly contracted, the lumen becomes narrow, blood flow is sharply reduced, and in severe cases, the lumen can be completely occluded, causing the corresponding symptoms of ischemia and hypoxia, which can be cerebral vasospasm, coronary vasospasm and so on.
Cerebral vasospasm is often secondary to aneurysmal subarachnoid hemorrhage, smooth muscle contraction of the cerebral vascular wall, resulting in cerebral ischemia and hypoxia, different parts of the lesion may have different manifestations, such as loss of consciousness, headache and even paralysis.
Vasospasm occurs in other parts of the body can cause related manifestations, such as occurs in the heart coronary artery, coronary artery spasm can cause angina pectoris, myocardial infarction, etc., manifested as pain in the heart area.
