多层螺旋CT血管成像在双主动脉弓畸形中的诊断价值

目的探讨多层螺旋CT血管成像在双主动脉弓畸形中的诊断价值。方法回顾性分析2012年6月至2015年6月于我院行多层螺旋CT血管成像和超声诊断共120例患者的临床资料,记录患儿的主动脉弓畸形发生情况以及对多层螺旋CT血管成像诊断主动脉弓畸形的结果进行分析。结果多层螺旋CT血管成像结果显示55例行多层螺旋CT血管成像的患儿中16例患儿的降主动脉横断面位置明显右移,13例患儿可见升主动脉分叉,7例患儿合并房间隔缺损,4例合并肺动脉瓣狭窄。多层螺旋CT血管成像的阳性诊断率72.7%,明显高于超声诊断的阳性诊断率,差异有统计学意义(P0.05)。结论多层螺旋CT血管成像在双主动脉弓畸形的诊断阳性率明显高于超声检查,在双主动脉弓畸形的诊断中有应用价值。

The Value of Multi-slice Spiral CT Angiography in the Diagnosis of Double Aortic Arch Deformity

Objective To explore the value of multi-slice spiral CT angiography in the diagnosis of double aortic arch deformity.Methods A retrospective analysis of clinical data of 120 patients receiving multi-slice spiral CT angiograph and echocardiography from June 2012 to June 2015 in our hospital was conducted, record the occurrence of double aortic arch and analyze the result.Results The imaging results showed that the location of cross section of descending aorta in 16 cases of patients was right-shifted, the ascending aorta in 13 cases of patients were bifurcated, 7 cases of patients were with atrial septal defect and 4 cases of patients were with pulmonary valve stenosis. The positive diagnostic rate of multi-slice spiral CT angiography was 72.7%, which was significantly higher than that of echocardiography(P<0.05).Conclusion The rate of multi-slice spiral CT angiography in the diagnosis of double aortic arch was significantly higher than that of the echocardiography, it has application value in the diagnosis of double aortic arch deformity.
