急性脑梗死OCSP分型与颈动脉粥样硬化的相关性

目的 探讨急性脑梗死患者OCSP分型与颈动脉粥样硬化的相关性.方法 对146例急性脑梗死患者进行OCSP分型,应用彩色多普勒超声检测脑梗死患者颈动脉病变情况,分析颈动脉粥样硬化斑块与急性脑梗死OCSP各亚型的相关性.结果 急性脑梗死患者OCSP各亚型构成比为:部分前循环梗死为43.1%,腔隙性梗死为39.0%,后循环梗死为11.6%,完全前循环梗死为6.3%;急性脑梗死患者颈动脉有斑块者占70.5%,完全前循环梗死+部分前循环梗死组患者中占斑块检出率的55.3%;不稳定性斑块患者的检出率为46.9%、斑块≥4个的患者为33.3%、斑块平均个数为3.26±1.87个,明显高于其它两型(P0.05).结论 颈动脉粥样硬化斑块及斑块稳定性、个数与完全前循环梗死和部分前循环梗死的形成密切相关,对颈动脉彩色多普勒超声检查有斑块检出者应尽早进行干预.

Correlation Study on Subtype of OCSP and Carotid Artery Atherosclerosis in Patients with Acute Cerebral Infarction

Aim To explore the correlation between subtype of OCSP and carotid artery atherosclerosis in patients with acute cerebral infarction. Methods 146 patients with acute cerebral infarction were classified into 4 major ischemic stroke subtypes based on OCSP criteria and carotid artery were detected by color doppler of ultrasound.The relationship between them was analyzed. Results The percentage of each acute cerebral infarction OCSP subtypes of patients was as following: PACI 43.1%,LACI 39.0%,POCI 11.6%,TACI 6.3%;of all the patients,the 70.5% had carotid artery with plaque.In the TACI+PACI group,55.3% were detected with plaques;the mean plaques were 3.26±1.87,33.3% were detected with more than four carotid plaques and 46.9% were detected with unstable plaques,which were significantly higher than those in other two groups(P><0.05),whereas,there was no difference between LACI group and POCI group(P>0.05). Conclusion There is strong correlation between PACI and TACI and carotid atherosclerotic artery plaque,plaque stability and number.Actions should be taken to patients with carotid artery plaque detected by color doppler ultrasound.
