Correlation Study Of Cerebral Artery Microembolism Detection In Patients With Acute Cerebral Infarction

Objective Explore the microembolic signal positive risk factors for stroke on acutecerebral infarction patients underwent carotid ultrasound and microemboli monitoring, inparticular, and the correlation of carotid atherosclerotic plaques, microemboli-positive in thecerebral infarctionrole in the pathogenesis and clinical significance.Methods Select the neurology hospital to meet the requirements of patients with acutecerebral infarction, the clinical data were recorded, were the monitoring of micro-emboli andcarotid ultrasonic testing, the nature of the records of the number of microemboli, locationand carotid atherosclerotic plaquelocation and quantity.The statistical analysis of explore ofmicroemboli positive relationship with carotid artery atherosclerotic plaque and stroke riskfactors.Results (1)108patients monitored40cases of the MES-positive rate of37.04%,recorded a total of MES total of146, the microemboli intensity of5.1~27.2dB, the leftmonitor to the MES for20cases, the right side in11cases,9cases of bilateral.65cases ofcarotid artery plaque, plaque a rate of60.19%,31cases of unstable plaques, occupy47.69%of the plaque number of cases; plaque located in the left side of the17cases, the right side in13cases,35cases of bilateral.(2)Carotid plaque group MES-positive rate47.69%and20.93%of the plaque group difference was statistically significant; unstable carotid plaque groupMES positive rate of64.52%with stable plaque group32.35%,There were significantdifferences.(3)A carotid artery plaques MES positive rate of41.18%with two and multipleplaques by50%difference was not statistically significant.(4)Monitoring the group of carotid artery plaque to the MES is located in the left side of19cases, the right side in8cases,4cases of bilateral, left and right side of the MES-positive rate difference was statisticallysignificant, the left side of MES-positive rate.(5)Common carotid artery plaques MES positiverate of36.67%and non-common carotid artery plaque57.14%of the difference was notstatistically significant;The carotid bifurcation MES positive rate of plaque by60%andnon-carotid artery bifurcation plaques33.33%difference was statistically significant to thecarotid bifurcation MES positive rate higher; Carotid artery at the beginning of MES positiverate of plaque by38.46%and non-carotid artery plaque53.85%were no significantdifferences.(6)Logistic regression analysis found that carotid artery plaque, hyperlipidemia,diabetes, positive microemboli a risk factor.Conclusion (1)Microemboli-positive rate,unstable plaques in patients with acutecerebral infarction associated with carotid artery plaque in the cerebral blood flow more easilyoff the formation of microemboli, the activity of unstable plaques in the cerebral infarctionone of the factors.The occurrence of microemboli higher than the right side of the left side ofthe carotid bifurcation.(2)of the carotid atherosclerotic plaque, hyperlipidemia, and diabetes isa major contributing factor to cerebral artery microemboli;(3)TCD microemboli monitoringcarotid ultrasound stroke risk factors for population census has important clinical value.
