通过核磁共振成像、超声心动图、心血管造影、螺旋ＣＴ等各种方法测量肺血管大小，计算肺动脉总干／主动脉比值、ＭｃＧｏｏｎ指数——即左肺动脉（ＬＰＡ）与右肺动脉（ＲＰＡ）直径之和／降主动脉直径、Ｎａｋａｔａ指数（ＬＰＡ、ＲＰＡ近第一支分支处血管截面积相加／体表面积）、ＰＶＩ指数（所有肺静脉入心房近端处的截面积相加／体表面积），对各类肺血减少先天性心脏病手术预后进行评估。肺血管大小与右心室／左心室峰压比、肺血管顺应性密切相关，并可影响肺血管阻力。ＭｃＧｏｏｎ指数、Ｎａｋａｔａ指数、ＰＶＩ指数与术后血液动力学、术后低心排的发生、术后生存率高度相关。
Pulmonary vascular size was measured by various methods such as magnetic resonance imaging, echocardiography, cardiovascular angiography, and spiral CT, and the ratio of total dry-aortic ratio of the pulmonary arteries was calculated. The McGoon index, the diameter of the left pulmonary artery (LPA) and the diameter of the right pulmonary artery And / descending aorta diameter, Nakata index (LPA, sum of vascular cross-sectional area / body surface area at the first branch of RPA), PVI index (sum of cross-sectional area of all pulmonary veins into proximal atrium) To assess the prognosis of various types of pulmonary blood surgery to reduce congenital heart disease. Pulmonary vascular size and right ventricular / left ventricular peak pressure ratio, pulmonary vascular compliance are closely related, and may affect pulmonary vascular resistance. McGoon index, Nakata index, PVI index and postoperative hemodynamics, postoperative low cardiac output, postoperative survival rate is highly correlated.
