Correlation Between 3D-ASL Manifestations Of Posterior Circulation Transient Ischemic Attack And TCM Syndrome Types

Objective:to analyze the correlation between 3D-ASL imaging and TCM syndrome types of vertigo in patients with posterior circulation transient ischemic attack,so as to provide reference for the diagnosis and treatment of posterior circulation TIA with integrated traditional Chinese and Western medicineMethods:From July 2018 to February 2021,collecting 104 patients who diagnosed with posterior circulation transient ischemic attack in the Department of Neurology,Affiliated Hospital of Chengdu University of traditional Chinese medicine.The general situation,past history,four diagnostic data of traditional Chinese medicine and cerebral perfusion of 3D-ASL were collected.Results:A total of 104 patients with posterior circulation TIA were included in this study,including 41 males and 63 females.There were more female patients than male patients(P < 0.05).There were differences in age distribution,including 24 middleaged patients and 80 elderly patients,mainly elderly patients(P < 0.05).There were differences in the distribution of body mass index: 3 patients were too light,42 patients were normal,50 patients were overweight,and 9 patients were obese,indicating that normal and overweight patients were the main ones(P < 0.05);The distribution of perfusion: normal perfusion in 57 cases(54.8%),decreased perfusion in 44 cases(42.3%),increased perfusion in 3 cases(2.9%);7 patients showed decreased perfusion in anterior circulation,10 patients showed decreased perfusion in anterior circulation and posterior circulation,27 patients showed decreased perfusion in posterior circulation;Male patients,elderly patients and patients with hypertension,diabetes or hyperlipidemia were more likely to have decreased perfusion(P<0.05).The TCM syndrome types were phlegm retention syndrome in 48 cases(46.2%),liver yang hyperactivity syndrome in 27 cases(26.0%),Qi and blood deficiency syndrome in 15cases(14.4%),kidney essence deficiency syndrome in 8 cases(7.6%),blood stasis obstructing collaterals syndrome in 6 cases(5.8%),excess syndrome in 81 cases and deficiency syndrome in 23 cases.There was a significant correlation between gender,age and the distribution of TCM syndrome types(P<0.05).The deficiency of Qi and blood in female patients was more than that in male patients,and the hyperactivity of liver Yang in male patients was more than that in female patients,while the deficiency in elderly patients increased.There was no correlation between blood pressure,blood glucose and dyslipidemia and the distribution of TCM syndrome types(P>0.05);There was no significant difference in the distribution of TCM syndrome types between the normal perfusion group and the decreased perfusion group(P>0.05),but there was difference in the distribution of TCM syndrome types between the patients with decreased perfusion(P<0.05),mainly with phlegm retention syndrome;there was difference in the distribution of TCM syndrome types between the patients with decreased posterior circulation perfusion in 3D-ASL(P<0.05),mainly with phlegm retention syndrome.Conclusion: 1.In this study,the 3D-ASL of patients with posterior circulation TIA showed:42.3% perfusion was decreased,54.8% perfusion was normal,and 3 patients had increased perfusion.Male patients,elderly patients and patients with hypertension,diabetes or hyperlipidemia are more likely to have decreased perfusion;2.The TCM syndrome types of posterior circulation TIA patients are mainly phlegm retention syndrome and excess syndrome.The deficiency of Qi and blood in female patients is more than that in male patients.The hyperactivity of liver Yang in male patients is more than that in female patients;3.The distribution of syndrome types of patients with decreased posterior circulation perfusion in 3D-ASL is different,mainly phlegm turbidity syndrome.
