MSCT血管仿真内窥镜技术在成人先天性主动脉瓣二瓣化畸形诊断中的应用

Multi-slice Spiral CT Virtual Endoscopy in Diagnosis of Adult Bicuspid Aortic Valve Deformity

目的:探讨MSCT血管仿真内窥镜技术(CTVE)在诊断成人先天性主动脉瓣二瓣化畸形中的应用价值。方法:本院自2010年3月至2015年8月应用128层螺旋CT进行冠状动脉CT血管造影(CTCA)检查,发现主动脉瓣区钙化患者中8例主动脉瓣叶在CTVE下直观地呈现为二瓣化,并同时测量主动脉瓣瓣膜厚度及升主动脉宽度。结果:8例主动脉瓣区钙化患者主动脉瓣在CTVE下表现为二瓣化畸形,同时通过CTCA检查,发现合并的其他心血管畸形,其中6例升主动脉增宽,1例左冠状动脉起源异常。并发现5例主动脉瓣增厚,3例主动脉瓣膜未见明显增厚。结论:CTCA检查中应用CTVE可以直观地及三维地显示主动脉瓣的结构,在诊断成人先天性主动脉瓣二瓣化畸形上可以与彩色多普勒超声心动图互相补充,并可以发现合并的其他心血管畸形及观察冠状动脉情况,从而排除其他疾患。

Objective： To investigate the clinical value of MSCT virtual endoscopy （CTVE） in diagnosis of adult bicuspid aortic valve deformity. Methods： From March 2010 to August 2015, eight cases with calcification of aortic valve underwent 128-slice spiral CT coronary angiography （CTCA） examination were presented bicuspid aortic valve deformity intuitively under CTVE. The thickness of aortic valve and the maximum diameter of the ascending aorta were measured. Results： Eight cases with calcification of aortic valve were presented bicuspid aortic valve deformity intuitively under CTVE, through the CTCA, other merger cardiovascular malformations can be found, and included 6 cases of aortic widened, one case of abnormal left coronary artery origin. And thickened aortic valve was found in 5, no thickening of the aortic valve in 3.Conclusion： Application of CTVE in CTCA examination visualize the structure of the aortic valve, and can find other vascular malformation, observe coronary artery, so as to rule out other diseases. Moreover, CTVE and color Doppler echocardiography can complement each other.
