评价磁共振成像(MRI)及电影磁共振成像(cine-MRI)在小儿法乐四联症的诊断价值。采用MRI及cine-MRI成像技术,检查了25例法乐四联症患儿,并与超声心动图(UCG)和心血管造影(CAG)进行比较,全部病例均经手术证实。结果表明,MRI及cine-MRI能清晰地显示法乐四联症的室间隔缺损,主动脉骑跨,肺动脉狭窄和右心室肥厚的基本病理改变,可进行定性及定量诊断。本组资料显示,MRI、UCG、及手术(OP)对室间隔缺损大小测量无显著性差异(P=0.328)。MRI对主动脉骑跨率测量与UCG、CAG结果相一致。肺动脉主干及左、右肺动脉内径测量与UCG、CAG相关有显著性。MRI及cine-MRI能对法乐四联症基本病理畸形做出准确诊断,手术证实与CAG诊断结果基本相同,对左、右肺动脉的显示优于UCG,可做为法乐四联症术前诊断的主要检查方法。

The larger AoD/LVDd were, the more serious of the degree of aortic overriding ventricular septum, PS and/or RVOS were, and the worse the operative effects were. Conclusions: AoD/LVDd is a simple and effective index to assess the degree of PS and F4, and to predict the operative effect of F4.

AIM: To analyze structure of persistent truncus arteriosus(PTA), hemodynamics, and explore selection of view. MOTHODS: Color Doppler ultrasound system were used to detect two dimensional echocardiography (2DE) and color Doppler flow imaging (CDFI) of 11 patients suspected with PTA. All cases underwent assessment of the intracardic structures by subcastal, parasternal and suprasternal views. RESULTS: Among the 11 cases of PTA, 1 case of pulmonary artersia was diagnosed by 2DE and CDFI. 11 case of PTA was performed with angiocardiography. 10 cases were classified by 2DE and CDFI, which were 2 cases of type 1, 1 type II, 4 type III, and 3 type Ⅳ. 2DE and CDFI showed the truncus arteriosus originated from both ventricles equally in 5 cases and predominanly from the right ventricle in 6 cases with overriding rate ≥60%.The number of the truncal cusps included 1 case of bicuspid, 1 case of quadricuspid and 9 cases of tricuspid. CONCLUSION: 2DE and CDFI should be used to identify pathologic anatomy of abnormal structure of PTA and hemodynamics features. The diagnosis rate is high (91%).
