摘要
目的:评价MRI在先天性主动脉缩窄中的诊断作用。材料与方法:分析14例主动脉缩窄的MRI,并与超声心动图(UCG)和心血管造影(CAG)进行比较,其中12例经手术证实。结果:MRI显示了14例主动脉缩窄及缩窄的程度、形态(细管状狭窄6例,环状狭窄5例,隔膜形狭窄3例),并显示了缩窄处与左锁骨下动脉的关系。合并畸形有:10例室间隔缺损,13例动脉导管未闭,1例马凡氏综合征,10例主动脉弓发育不良。比较三种影像方法:MRI诊断能力明显优于UCG,基本达到CAG水平。结论:在先天性主动脉缩窄的临床诊断中,MRI应成为主要或首选检查方法。
Purpose:To thoroughly evaluate the clinical efficacy of MRI in diagnosis of congenital coarctation of the aorta. Materials and methods: 14 cases MRI of coarctation of the aorta were analysed and compared with echocardiography (UCG) and cardioangiography (CAG), and in which 12 cases were confirmed by operation. Results: Utilizing MRI, it was possible to acqiure the following information concering coarctation of the aorta: the length and the severity of the lesion; the shape of coarctation including tubular shape (6 cases); hourglass shape (5 cases), and membranous shape (3 cases); the relationship of the site of coarction to the left subclavian artery. The associated anomolies included: Ventricular septal defect (10 cases), patent ductus arterious (13 cases), hypoplastic aortic arch (10 cases), and Marfan's syndrome (1 case). It was found that the diagnostic utility of MRI was superior to that of UCG and approched that of CAG. Conclusion: MRI should be a important or/and initial method of examination and might partly displace CAG as the final method used in the diagnosis of coarctation of the aorta.
