Seasonal alternation, temperature fluctuation, is one of the high risk of cardiovascular and cerebrovascular disease. After the beginning of autumn, slowly ushered in the autumn, occasionally a rain will bring coolness. So in this case to remind patients with cerebral aneurysms, when the temperature changes, mood swings, will cause a sudden increase in blood pressure, which can easily lead to rupture of cerebral aneurysms.
A brain aneurysm is due to cerebral arterial wall partial congenital defect and cavity pressure, cerebral arterial wall thinning and abnormal swelling resulting from the appearance, as if the artery grew out of a balloon like "wart", hence the name "aneurysm". The occurrence of cerebral aneurysms is related to hypertension, cerebral arteriosclerosis, infection, trauma and so on. Cerebral aneurysms and vascular wall thinning bulge, when large temperature changes, mood swings, can cause blood pressure suddenly increased, easily lead to rupture of cerebral aneurysm.
Experts said that 80% of spontaneous subarachnoid hemorrhage is caused by a ruptured cerebral aneurysm, cerebral aneurysm rupture and hemorrhage of the first mortality rate was 15%-20%, if the first bleeding patients after no death, also did not receive timely treatment, will soon happen second times out of the blood, then the mortality rate is as high as 80%. Therefore, the purpose of the treatment of cerebral aneurysms is to prevent aneurysm rupture bleeding or rupture. If the clinical diagnosis of cerebral aneurysms, even if there is no rupture also need to be treated, because it may break at any time.
