The complications of acute cerebral infarction mainly include the following: 1. Cerebral hemorrhage: atherosclerosis of large arteries is the main cause of cerebral infarction, and most of the atherosclerosis is systemic. When acute cerebral infarction occurs, it is also very likely to be complicated by stenosis or occlusion of coronary arteries of the heart, and myocardial infarction occurs. And when the occlusion of large cerebral arteries, it will cause large cerebral infarction, and reperfusion will cause damage, so it may be complicated by cerebral hemorrhage; 2, asphyxia and aspiration pneumonia: cerebral infarction symptoms in addition to hemiplegia, there are very common symptoms such as dysphagia, speech is unfavorable. When a patient will have dysphagia and unfavorable speech, feeding too fast, especially when the liquid diet is too fast, because of dysphagia, the food can not enter the esophagus quickly, but in turn into the airway, it will be complicated with aspiration pneumonia, which is often more dangerous. If there is a large piece of food solid into the airway will lead to choking, so choking and aspiration pneumonia is also a common complication of acute cerebral infarction; 3, pressure ulcers: because of the weakness of activity, patients with acute cerebral infarction need to be bedridden for a long time, and if they don’t turn over in time, pressure ulcers are very likely to appear in the compressed parts such as the heel, the sacrococcygeal region, the back, etc. So, patients with acute cerebral infarction should be careful to make sure that they have the proper treatment for the pressure ulcers. Therefore, in order to avoid pressure sores, patients with acute cerebral infarction must turn over in time and take care of them in time.
