Correlation Of The Extracranial Or Intracranial Artery Stenosis And Stroke In Progression

Objective To observe the relationship between the extracranial or intracranial artery stenosis and stroke in progression(SIP), further discussion the risk factors of SIP.Methods120hospitalized patients(came from the Beijing Military General Hospital)with acute cerebral infarction were assigned into our study, randomly allocated into two groups:stroke in progression(SIP) group(n=60) and stable cerebral infarction group(n=60). After admission of hospital,all of them were examined by head/neck CTA/MRA and ultrasonography examination and it was determined whether the extracranial or intracranial artery stenosis degree is associated with stroke in progression.Results The incidence of the extracranial or intracranial artery stenosis in progress group was obviously higher than stable cerebral infarction group. The extracranial or intracranial artery stenosis is associated with stroke in progression. Logistic regression analysis show that hypertension, hyperlipemia, homocysteine and middle cerebral artery stenosis were the independent risk factors to stroke in progression (OR=3.32,95%CI:1.01-5.03; OR=2.74,95%CI:1.07-4.53;OR=2.48,95%CI:1.09-4.45; OR=5.75,95%CI:1.19-6.65; OR=2.59,95%CI:1.04-4.34)Conclusion The extracranial or intracranial artery stenosis may be closed related to ischemic stroke in progression, through positive blood vessel evaluation to take timely intervention can delay the progression of stroke.
