Abstract:
Objective To analyze the application value of multislice spiral CT in diagnosis of children malformation of large blood vessels outside the heart.Methods The diagnosis results were compared between echocardiography and multislice spiral CT in 110 children with congenital heart disease,and the children had been confirmed by operation.Congenital heart disease was divided three kinds according to the region:heart,connections between heart and large blood vessels and large blood vessels outside the heart.Results One hundred and ten children with congenital heart disease were selected,and they had 366 malformations.The accuracy rates of echocardiography and multislice spiral CT were 90.7％ (332/366) and 95.6％ (350/366) respectively,and there was no statistical difference (x2 =3.284,P =0.070).In 366 malformations,160 malformations were in heart region.The accuracy rates of echocardiography and multislice spiral CT were 98.1％ (157/160) and 97.5％ (156/160) respectively,and there was no statistical difference (x2 =0.776,P =0.378).There were 55 malformations in connections between heart and large blood vessels.The accuracy rates of echocardiography and multislice spiral CT were 94.5％ (52/55) and 100.0％ (55/55) respectively,and there was no statistical difference (x2 =3.083,P =0.243).There were 151 malformations in large blood vessels outside the heart.The accuracy rates of echocardiography and multislice spiral CT were 81.5％(123/151) and 92.1％ (139/151) respectively,and there was statistical difference (x2 =7.377,P =0.01).Conclusion Multisltce spiral CT has great application value in diagnosis of children congenital heart disease,especially in malformation of large blood vessels outside the heart.
