Abstract:
Purpose To investigate the relationship between imaging characteristics and shunt grading in acute cerebral infarction patients with right-to-left shunt.Materials and Methods The clinical and imaging data of 697 acute cerebral infarction patients who were hospitalized in the Second Affiliated Hospital of Nanchang University from January 2019 to December 2021 were collected,and the patients were divided into right-to-left shunt negative group(443 cases)and right-to-left shunt positive group(254 cases)according bubble test,compared the difference in demographic data and imaging characteristics between the two groups.In the shunt positive group,the imaging characteristics of the two groups of patients and their relationship with the shunt grade were analyzed.Results There were no statistical differences in gender,age,smoking,hyperlipidemia and history of coronary heart disease between the two groups(P>0.05),but there were statistical differences in the history of hypertension(OR=0.533,95%CI 0.380-0.748),diabetes(OR=0.649,95%CI 0.422-0.999)and cerebral infarction(OR=0.275,95%CI 0.136-0.555)(all P<0.05).The imaging characteristics of the two groups of patients showed that there were significant differences in the number of infarct foci(χ2=53.957,4.219;both P<0.05),but there was no statistical difference in the infarct location between the two groups(P>0.05).Among the patients with acute cerebral infarction combined with positive bubble test,the imaging manifestations of grading I and II patients were mainly unilateral anterior circulation or posterior circulation infarction,and deep and single infarction were more common.In patients with grading III and IV shunts,multiple infarcts with combined bilateral anterior and posterior circulations were more common.Conclusion The imaging manifestations of patients with acute cerebral infarction combined with right-to-left shunt have their own characteristics.Bubble test has high sensitivity in the diagnosis of right-to-left shunt.The comprehensive analysis can provide certain guidance for clinical practice.
