Stroke: Classification of ischemic stroke based on high-risk cervical artery plaques of non-conclinoe stenosis

!---- 50% of the background and objective cervical artery plaques and tube cavities may not be the main cause of the stroke mechanismthis study to assess the value of reclassification of stroke by reference to non-tube stenosis high-risk plaquesmethodthis study included patients with pre-circulatory infarction and cerebral MRI and neck MRAhigh-risk plaques are bleeding inside the plaques that are examined by a neck MRAuse DWI to identify the location of the infarctionthe use of blindness by neuroradiologists to assess the hemorrhage and infarction position of plaque respectivelyuse McNemar to test the matching data to compare the sidedifference of intracranial bleeding and intracranial infarction positionsregardless of the degree of cervical artery stenosis, there will be plaque intrastele bleeding and the presence of cerebral infarction on the same side as a major atherosclerosis strokeresults in a total of 579 patients with acute ischemic stroke in 1721 casesin patients with atherosclerosis (RR, 3.7 (95% CI, 2.2-6.1), cryptite (RR, 2.1 (95% CI, 1.4-3.1)) and heart-induced embolism (RR, 1.7 (95% CI, 1.1-2.4) patients, high-risk plaques are more common in cerebral palpitations and cervical deathsthere was no significant difference in the placement of high-risk plaques relative to the position of cerebral infarction (RR, 1.2 (95% CI, 0.4-3.5)) and other causes of stroke (RR, 1.5 (95% CI, 0.7-3).)in the consideration of the same side of high-risk plaque, 88 (15.2%) patients had a change in the mechanism: 38 (22.6%) heart-induced embolism, 6 (8.5%) cavity cerebral infarction, 3 (15.8%) other causes were changed to multiple;concluded that high-risk plaques in the neck artery were common in the same side of the carotid artery of the cerebral infarctionreclassify up to 15% of cases based on the location of high-risk plaques in the carotid artery
