The correlational study of migraine without aura in Xining and right-to-left shunt(RLS)through cTCD

Objective To research the incidence rate of right-to-left shunt(RLS)in patients of migraine without aura in Xining through Transcranial Doppler Bubble Test.Methods 273 cases with migraine chosen as the case group in Xining First People’s Hospital from November 2018 to July 2020,and 200 healthy physical examinees as the control group.All the subjects recceived Transcranial Doppler Bubble Test in order to observe the incidence rate of RLS.Results 107 cases in the case group had RLS positive rate(39.2%),including 28 cases at level Ⅰ with positive rate 10.3%,25 cases at level Ⅱ(10.2%),24 cases at level Ⅲ(8.8%)and 30 cases at level Ⅳ(10.9%).65 subjects in the control group had RLS positive rate 32.5%,including 22 cases at level Ⅰ with positive rate 11%,14 cases at level Ⅱ(7%),11 cases at level Ⅲ(5.5%)and 18 cases at level Ⅳ(9%).There was no statistic difference at level I(P>0.05)between the two groups,while there were statistic differences in other sets of data(P<0.05).Conclusions The positive rate of RLS in the case group is higher than that in the control group.The incidence rate of RLS of patients of migraine without aura and of healthy people living at middle-high altitudes is rather high.
