体、肺循环血流量、Qp/Qs比值和(Qp-Qs)是衡量左向右分流型VSD、ASD_(Ⅱ)严重程度和确定手术指征的重要依据。本文报告应用2D-PDE体积血流测量法测定上述血流动力学指标,并与右心导管测值进行对照的结果,对这一方法的可靠性、局限性和影响因素进行探讨。
Body, pulmonary blood flow, Qp / Qs ratio and (Qp-Qs) is an important basis to measure the severity of left-to-right shunt VSD, ASD Ⅱ (Ⅱ) and to determine surgical indications. In this paper, the application of 2D-PDE volume flow measurement method to measure the above hemodynamic parameters, and the right heart catheterization measured the results of the comparison, the reliability of the method, limitations and influencing factors are discussed.
