摘　　要：目的 探讨心电门控双源CT血管造影(DSCTA)用于先天性单心室(SV)合并单心房(SA)的诊断价值。方法 对27名患有单心室合并单心房的严重复杂型先心病患者进行DSCTA检查,进行诊断分型并归纳其合并的畸形情况。结果 27例患者依据主心室腔的形态学特征分类,左心室型8例、右心室型12例、不确定型7例,相应占比分别为29.63%、44.44%、26.00%。心房正位9例(9/27,33.33%),心房反位1例(1/27,3.70%),心房不定位17例(17/27,62.9 6%,其中包含1例左心房异构,16例右心房异构);合并畸形30种188处。左室双出口、右室双出口和小梁囊在三种类型单心室之间具有统计学差异(P<0.05)。不确定型与左心室型单心室在右房异构方面存在统计学差异(P<0.05),其他方面没有统计学显著差异(P>0.05)。DSCT与经胸超声心动图在评估左肺动脉直径、腹主动脉直径以及McGoon指数方面存在相关性。结论 DSCTA可准确诊断单心室、单心房及合并畸形,为外科手术适应症、风险评估提供参考。Objective To investigate the value of ECG-gated dual-source computed tomography angiography(DSCTA) in the diagnosis of single atrium(SV) and single atrium(SA).Methods DSCTA was performed in 27 patients with severe complex congenital heart with disease SV combined SA.The classification diagnosis was made,and the complicated deformities were summarized.Results According to the morphological characteristics of the main ventricular cavity,the 27 patients were classified as left ventricular type(8 cases),right ventricular type(12 cases) and uncertain type(7 cases)(29.63%,44.44%and 26.00%,respectively).Atrial situs so lit us was found in 9(9/27,33.33%),atrial situs inversus was found in 1(1/27,3.70%) and atrial situs ambiguous was found in 17(17/27,62.96%,including right atrial isomerism in 16 and left atrial isomerism in 1 patient).The patients complicated with 30 kinds,totally 188 deformities There were statistically significant differences between the left ventricular double outlet,right ventricula r double outlet and trabecular ca psule of three types of single ventricle(P<0.05).There were statistical differences in right atrial isomerism between uncertainty type and left ventricular type single ventricle(P<0.05),and no statistically significant differences in other aspects(P>0.05).Left pulmonary artery diameter,abdominal aorta diameter and McGoon index measured by two methods of DSCT and TTE were correlated.Conclusion DSCTA can accurately diagnose single ventricle,single atrium and associated malformations,and provide reference for surgical indications and risk assessment.
