SA: small aneurysm.MA: medium aneurysm.GA: giant aneurysm. CALs= dilation +SA+MA+GA
As shown in Table 3, there was nostatistically significant difference in the incidenceof CALs between the twogroups at 7days (P =0.650,P >0.05), and no statistically significant difference at 1 month, 3 months and 6 months after hospital discharge(P =0.202,P >0.05;P =1.000,P >0.05; P = 0.674,P>0.05).But at 12 months and 24 months of follow up, the MPT group had a higher incidence of CALs compared with the second IVIG treatment group (P = 0.043,P <0.05; P = 0.033<0.05).
