摘要
探讨单心室的双源CT(DSCT)特征及DSCT对单心室患者的诊断价值。回顾分析2009年-2011年期间四川大学华西医院14例单心室患者的DSCT影像表现,并与手术及心导管结果对照。结果发现:(1)按照Anderson分型方法,14例单心室患者中,左心室型7例(50.0%),右心室型3例(21.4%),未定心室型4例(28.6%)。(2)合并畸形:肺动脉狭窄11例(78.6%),双侧上腔静脉6例(42.9%),房间隔缺损5例(35.7%),共同房室瓣5例(35.7%),单心房4例(28.6%),大动脉转位3例(21.4%),内脏反位3例(21.4%),心房异构2例(14.3%),右位心2例(14.3%),右位主动脉弓2(14.3%),心耳并置1例(7.1%),完全性肺静脉异位引流1例(7.1%),无脾综合征1例(7.1%),动脉导管未闭1例(7.1%)。(3)左心室型的附属心腔多位于主心腔的前方,占5例(71.4%);而右心室型的附属心腔均位于主心腔的后方,占3例(100%)。(4)主、肺动脉以共同起于主心室多见,占8例(57.1%);主动脉瓣多位于肺动脉瓣的右侧,占9例(64.3%)。(5)其中10例单心室分型与手术结果对照,符合率达100%。DSCT对单心室诊断分型的准确率高,对主、肺动脉及冠状动脉的病变也可很好地显示。
This paper was aimed to explore the features of single ventricle with dual source computed tomography （DSCT） and the value of the modality in diagnosis of the single ventricle disease. Dual-source computed tomography imaging of 14 cases of single ventricle compared with the results of surgery and cardiac catheter were retrospectively analyzed. Firstly, 14 cases were classified into three types according to Anderson classification method, including 7 cases （50.0 %） left ventricular type, 3 cases（21.4 % ）right ventricular type and 4 cases （28.6% ）undecided ventricular type. Secondly, in accompanying malformation respect, pulmonary stenosis, bilateral superior vena cava, atrial septal defect （ASD） and common atrioventricular valve were presented frequently. Thirdly, affiliated cardiac chamber of left ventricular type were mostly in front of the major cardiac chamber （5 cases, 71.4%）, while affiliated cardiac chamber of right ventricular type were behind of the major cardiac chamber totally. Fourthly, more than half of aortas and pulmonary arteries stemming from common cardiac chamber can be seen （8 cases, 57.1%）. Meanwhile the aorta valves were more on the right of pulmonary valve （9 cases, 64.3%）. The classification of 10 cases of single ventricle was compared with the results of surgery, and the coincidence rate is 100%. DSCT can diagnose the single ventricle disease accurately. The aorta, pulmonary artery and coronary artery can be displayed completely and simultaneously as well.
