Analyticce Study Of The Correlation Of Head And Neck Artery Stenosis And Plaque With The Progress And Recurrence Of Acute Cerebral Infarction

Objective Using256-slice CT angiography in patients with head and neck to assessacute cerebral artery lesions, analysis of head and neck artery stenosis and plaque withthe progress and recurrence of acute cerebral infarction, provide the basis for diseasediagnosis and treatment of cerebral infarction.Methods375cases of patients with acute cerebral infarction, are from January2012toJune2012in Hebei united university affiliated hospital neurology hospital patients on thebasis of progress sex stroke, such as diagnostic criteria are divided into: progress group(106cases), Non-progress group (269cases); According to the progress of time can bedivided into early progress type (85cases), the late progress type (21cases); According tothe criteria for the diagnosis of recurrent cerbral infarction were divided into: relapsegroup (14cases), first group (235cases). All the patients were256CT scanner for headand neck artery CTA examination to observe the vascular stenosis and plaque, head andneck were compared between the two groups artery stenosis and plaque were observedbetween the head and neck artery stenosis and plaque differences.Results1. Progress group and the Non-progress group head and neck artery stenosisand stenosis comparison: The positive rate of stenosis progression group higher positiverate difference between the two groups was significant (P<0.01), the progress of thegroup, severe proportion of stenosis higher, the difference was statistically significant(P<0.01).2. Progress group and the Non-progress group head and neck artery stenosiscomparison: Progress set higher proportion of middle cerebral artery stenosis, thedifference between the two groups was significant (P<0.05).3. Progress with the Non-progress group head and neck artery and plaque type comparison: Progress plaquepositive rate was higher, the difference was statistically significant(P<0.05), plaqueprogression group ulcers, high proportion of soft plaque in the Non-progress group, therewas significant difference between the two groups (P<0.05).4. Progress group and theNon-progress group of head and neck artery plaque occurrence site comparison: theproportion of plaque group BIF zone higher, the difference between the two groups wasstatistically significant (P<0.05), progression group vertebrobasilar spot block proportionthan the Non-progress group, there was significant difference between the two groups(P<0.05).5. Early and late progressive arterial stenosis in patients with progressivecomparison: severe greater than the proportion of early progress in the late progressivetype, the difference was statistically significant (P<0.05), the proportion of severestenosis in patients with early progressive higher than late progressive, the difference wasstatistically significant (P<0.05).6. Early and late progressive arterial and plaque inpatients with type comparison: Early progressive soft spots, ulcers spots higher than the proportion of late progressive, the difference was statistically significant (P<0.05).7.Recurrent head and neck with the first group artery stenosis and stenosis comparison: therecurrence rate was higher positive stenosis group, the positive rate of stenosis betweenthe two was significantly(P<0.01); mild recurrence group proportion of stenosis than thefirst group, the difference was statistically significant (P<0.01); relapse group, theproportion of severe stenosis were higher, the proportion of severe stenosis, the differencewas statistically significant (P<0.01).8. Compared with the first group recurrence of headand neck artery stenosis: the relapse group higher proportion of middle cerebral arterystenosis, the difference between the two groups was significant (P<0.01).9. Recurrenthead and neck with the first group arterial plaque type of comparison: the recurrent groupof soft plaque, plaque ulceration proportion higher, the difference was statistically(P<0.05); proportion of hard plaque recurrence group than the control group, thedifference was statistically significant (P<0.01).10. Relapse group and first acutecerebral infarction patients with head and neck artery plaque area comparison: relapsegroup of carotid artery bifurcation, middle cerebral artery plaque ratio is higher than thefirst group respectively, recurrence of vertebral basilar artery plaque ratio is lower thanthe incipient group, the difference was statistically significant(P<0.01).Conclusions1. Progressive cerebral infarction in patients with head and neck brainartery stenosis positive rate is high, and given priority to with moderately severe stenosis,more focused on middle cerebral artery stenosis site; And the progress of cerebralinfarction with head and neck at the same time supplying artery plaque type and location,the higher percentage of soft plaque and ulcer plaque, more focused on common carotidartery bifurcation and middle cerebral artery.2. Early development type in patients withhead and neck brain artery stenosis degree is relatively late progress seriously, and theplaque occurrence types is given priority to with soft plaque and ulcer.3. Recurrentcerebral infarction in patients with head and neck brain artery stenosis positive rate ishigh, and given priority to with moderately severe stenosis, more focused on middlecerebral artery stenosis site; And recurrent cerebral infarction with head and neck at thesame time supplying artery plaque type and location, the proportion of soft plaque andulcer plaque is higher, more focused on common carotid artery bifurcation and middlecerebral artery.
