Keywords: cerebral infarction etiology
Cerebral infarction is common in the elderly with ischemic cerebrovascular disease, and some patients can be maimed and the loss of labor and inconvenience, but reasonable treatment and rehabilitation, the majority of patients can be recovered or basic rehabilitation.
The incidence of cerebral infarction following two reasons:
1. Thrombosis: cause blood flow to slow down due to stenosis of cerebral arteriosclerosis, thrombosis. Its predilection branch of the middle cerebral artery, lenticulostriate arteries, etc..
2. Emboli cause: pathological anatomy studies found that nearly 50% of cerebral infarction caused by emboli, but clinical detected only 6% -20%, which is the most common cardiac (atrial fibrillation, myocardial infarction, valvular heart disease, endocarditis, cardiac enlargement, heart failure, etc.), accounting for 45%, the remaining 5% may come from artery atherosclerosis broken plaque off arteritic emboli and fat bolt and air embolism .
Cerebral thrombosis and cerebral embolism, caused by different causes, but on the pathophysiology of brain vascular occlusion, cerebral ischemia caused change, so the processing is basically the same.
