【摘要】 目的:评价前门控128层螺旋CT血管造影(CTA)诊断婴儿肺静脉畸形引流的应用价值。方法:肺静脉畸形引流患儿12例,采用128层螺旋CT前门控扫描,CTA图像后处理包括多平面重组(MPR)、容积重建(VR)、最大密度投影(MIP)及最小密度投影(MinP)。评价肺静脉畸形引流类型、气道异常及并发心内畸形。结果:完全型肺静脉畸形引流9例,包括心上型5例、心内型3例和心下型1例;部分型肺静脉畸形引流3例,包括心上型2例和心内型1例。并发房间隔缺损12例、动脉导管未闭2例、气道畸形3例。术前CTA诊断与手术结果完全相符。结论:前门控128层螺旋CTA在诊断婴儿肺静脉畸形引流中具有重要价值,能够为心外科手术方案制定提供可靠依据。更多还原

【Abstract】 Purpose: To evaluate the value of prospectively ECG-gated 128-slice spiral CTA in the diagnosis of anomalous pulmonary venous drainage(APVD).Methods: Twelve paediatric patients of APVD were undergone by prospectively ECG-gated 128-slice spiral CTA.The APVD types,airway abnormality and acompanied intracardiac malformation were evaluated by the multiplanar reconstruction(MPR),volume rendering(VR),maximum intensity projection(MIP) and minimum intensity projection(MinP).Results: Anomalous pulmonary venous drainage were shown in 9 cases,5 cases of them were central type,3 cases were intracardiac type,1 case was infracardiac type;partial anomalous pulmonary venous drainage were shown in 3 cases,2 cases of them were central type,1 cases was intracardiac type.Twelve cases were accopanied with atrial septal defect,2 cases with patent ductus arteriosus,and airway malformation was shown in 3 cases.The preoperative CTA diagnosis and the operation result was fully consistent.Conclusion: 128-slice spiral CTA with gating technique has important value in the preoperative diagnosis of pediatric pulmonary venous anomalous.更多还原
