Abstract:
Objective To investigate the association and difference between patent foramen ovale(PFO), atrial septal aneurysm(ASA), atrial septal defect(ASD) in normal controls and cryptogenic ischemic stroke(CS) in youth diagnosed by double source CT.Methods A total of 168 CS patients and 180 controls matched age and gender were included in the present study.The two groups were diagnosed by double source CT and clinical materials.The incident rate of PFO, ASA, ASD, the degrees of PFO, ASD,the lengths of PFO and difference between CS in two groups were analysed.Results The incident rates of PFO, ASA, ASD were 40.6%,10.7%,6.5% and 15.6%,3.3%,2.2% in CS groups and controls respectively(P<0.001).The incident rates of PFO merged ASA and ASA merged ASD were 6.0%,3.0% and 0%,0% respectively between two groups(P<0.001).The diameters of PFO, ASD were (1.71±0.62) mm,(3.42±0.72) mm and (0.85±0.51) mm,(2.45±0.42) mm in two groups respectively(P<0.001).The lengths of PFO were (14.6±3.8) mm and (8.2±2.3) mm in two groups(P<0.001).The correlations between stroke in two groups were no difference(P>0.001).Conclusion PFO,ASA and ASD are important to CS.While PFO,ASA and ASD can accurately be diagnosed by double source CT.
