Cerebrovascular Disease

Overview brain disease called cerebral vascular accidents, stroke or stroke. From the brain blood vessels, and lead to partial loss of nerve function characteristics of a group of diseases. Including intracranial and extracranial arteries, veins and venous sinus disease, but most common artery disease. Cause pathogenesis of hypertension, arteriosclerosis were the main risk factors, it was particularly prevalent in the elderly. According to the pathological changes into hemorrhagic and ischemic cerebrovascular disease two categories. I, intracranial hemorrhage. 1, subarachnoid hemorrhage. 1. Aneurysm Rupture : (1) of congenital aneurysm; (2) arteriosclerotic aneurysm; (3) bacterial aneurysm. 2. Vascular malformations. 3. Arteriosclerosis. 4. Intracranial vascular disease abnormal. 5. Other. 6. For unknown reasons. 2, brain hemorrhage. 1. Hypertensive cerebral hemorrhage. 2. Secondary to hemorrhagic infarction. 3. Tumor bleeding. 4. Blood disease caused. 5. Arteritis lead. 6. Drug-induced (anticoagulants, thrombolytic agents such as urokinase, etc.). 7. Cerebral vascular malformations or aneurysms. 8. Other. 9. Source is unknown. 3, epidural hemorrhage. 4, subdural hemorrhage. II, cerebral infarction (carotid and vertebral arteries a basilar artery system). 1, cerebral thrombosis. 1. Atherosclerosis lead. 2. Arteritis caused all kinds. 3. Traumatic and other physical factors. 4. Blood diseases such as erythrocytosis disease. 5. Drugs. 6. Other reasons. 2, cerebral infarction. 1. Cardiogenic. 2. Endogenous artery. 3. Other (fat suppository, air embolism, tumor thrombus, parasites suppository, phlebitis suppositories, etc.). 3, lacunar infarct. 4, vascular dementia. Five other. III, transient ischemic attack. A carotid artery system. 2, a vertebral basilar artery system. IV, cerebral insufficiency. V, hypertensive encephalopathy. Ⅵ, intracranial aneurysms. A congenital aneurysm. 2, atherosclerotic aneurysm. 3, bacterial aneurysm. 4, traumatic pseudoaneurysm. Five other. Vii. Intracranial vascular malformations. A brain artery and vein malformation. 2, cavernous hemangioma. 3, venous malformation. 4, the vein of Galen aneurysm. 5, carotid cavernous fistula. 6, capillary . 7, cerebral side hemangiomatosis. 8, intracranial vascular an extracranial traffic arteriovenous malformation. Nine other. Ⅷ, cerebral arteritis. 1, infectious arteritis. 2, aortoarteritis (aortic arch syndrome). 3, diffuse lupus erythematosus. 4, nodular polyarteritis nodosa. 5, temporal arteritis. 6, thrombotic occlusion happened. 7, leptospirosis arteritis. 8, other. Ⅸ, cerebral artery steal syndrome. Ⅹ, intracranial vascular disease abnormal. Ⅺ, intracranial venous sinus and cerebral venous thrombosis. 1, cavernous sinus thrombosis. Second, the superior sagittal sinus thrombosis. 3, straight sinus thrombosis. 4, the transverse sinus thrombosis. Five other. Ⅻ, cerebral arteriosclerosis.
