The aim of this study is to specify the feasibility and value of the diameter measurement of the jet of aortic insufficiency (AI) in colour Doppler. 68 consecutive patients had a supra-sigmoid angiography and a colour echo-Doppler. An aortic insufficiency was revealed 58 times by the angiography and Doppler. In all the cases except four, it has been possible to measure the jet diameter at the origin in para-sternal incidence in colour TM by confronting the images in great and small axis section. The Doppler results have been compared to the angiographic score in 4 grades according to Sellers classification. The jet diameter at the origin in colour TM is significantly different in groups I, II, III-IV. In the group III-IV, it is always higher or equal to 13 mm. The failures of quantification of the AI jet in colour Doppler are linked with the very eccentric nature of the jet or to the poor quality of the echo-Doppler imaging. On the whole, the jet diameter measurement proves to be a very useful element in the assessment of the gravity of an AI, particularly when it is a central and circular jet.
本研究的目的是明确彩色多普勒中主动脉瓣关闭不全（AI）射流直径测量的可行性和价值。连续68例患者接受了乙状结肠上血管造影和彩色超声多普勒检查。血管造影和多普勒检查发现主动脉瓣关闭不全58次。除4例病例外，在所有病例中，通过在大、小轴截面图像的对比，在胸骨旁位彩色TM上均可以测量射流起始处的直径。根据Sellers分类法，将多普勒结果与4级血管造影评分进行比较。彩色TM上射流起始处的直径在I、II、III-IV组中有显著差异。在III-IV组中，其始终大于或等于13mm。彩色多普勒中AI射流定量失败与射流非常偏心的性质或超声多普勒成像质量差有关。总体而言，射流直径测量被证明是评估AI严重程度的一个非常有用的指标，特别是当它是中心圆形射流时。
