摘　　要：目的探讨彩色多普勒血流会聚(FC)法测定主动脉瓣反流量的可行性。方法近端血流会聚角呈水平型的单纯性主动脉瓣反流患者27例,分别用FC法和心导管技术测定主动脉瓣反流量。结果FC法和心导管测定的主动脉瓣每搏反流量分别为(60±27)cm3和(58±25)cm3(P>0.05),两者存在良好相关性(r=0.91,P<0.01)。结论对于近端血流会聚角为水平型的主动脉瓣反流患者,FC法能准确测定其主动脉瓣反流量。Objective： To investigate the reliability of color Doppler flow convergence method for measurement of regurgitant volume of aortic regurgitation. Methods.. Using color Doppler flow convergence method and cardiac catheterization, regurgitant volume was calculated in 27 patients with isolated aortic regurgitation and a flat proximal flow convergence angle. Results： The regurgitant volume calculated by color Doppler flow convergence method and cardiac catheterization was （60±27）cm^3 and （58±25）cm^3 respectively （P 〉0.05）. There was an excellent correlation between the two methods （r=0.91, P〈0.01）. Conclusions： The color Doppler flow convergence method provides reliable measurement of regurgitant volume in aortic regurgitation with a flat proximal flow convergence angle.
