Analysis Of Related Factors Of Stroke Subtypes In Adult Moyamoya Disease

Objective:By analyzing the clinical and imaging data of adult moyamoya patients,explore the factors affecting the stroke subtype of adult moyamoya disease.Methods:The clinical data of moyamoya diease patients treated in our hospital between October 2016 and April 2018 were analysised retrospectively,including clinical data and imaging data.Results:1)The ratio of male to female patients was 1:1.3 and the average age was 47.47±11.46 years.There was no significant difference in age,gender,blood lipids and age between the two groups of patients with haemorrhagic disease and ischemia.2)Among all hemorrhagic patients,there were 6 cases of lobar hemorrhage,2 cases of basal ganglia hemorrhage,9 cases of intraventricular hemorrhage,and 1 case of thalamic hemorrhage.In 11 cerebral infarction patients,only 1 case was hypothalamic infarction,and the others were cerebral lobe infarction.3)Among the 32 stroke hemispheres,the hemorrhage group accounted for 21.9%and 25.0%of the stage Ⅲ and Ⅳ stages,and the ischemic group had the highest proportion of stage Ⅳ,Ⅴ,and Ⅵ,accounting for 15.6%,9.4%,and 12.5%.4)Whether there is a lack of PcomA is related to the subtypes of stroke;PcomA diameter is related to stroke subtypes;and the average diameter of PcomA in the hemorrhage group is greater than that of the ischemic group.Conclusion:1)Adult moyamoya disease occurs in 40-60-year-old patients,the ratio of male to female is close to 1:1.3.2)The common parts of hemorrhage is lobes and ventricle.The commom parts of infraction is lobes,the thalamus is rare.3)Patients withMMD with lack of PcomA are prone to ischemic stroke.Patients with intact PcomA are prone to hemorrhagic stroke.It is more likely to manifest as ischemia when the diameter of thePcomA is smaller,otherwise it manifests as hemorrhage.
