摘　　要：目的探讨无创性影像学诊断方法在非青紫型先天性心脏病(CHD)外周肺血管形态学上的诊断价值。方法对200例合并外周肺血管狭窄的非青紫型CHD患儿(其中164例合并外周肺血管狭窄,36例合并术后残存外周肺血管狭窄),在手术前或心导管造影(ACG)前行CT血管造影(CTA)和(或)磁共振成像血管造影(MRA)检查,分别测量外周肺血管狭窄处内径,并与手术或ACG实测值进行配对样本T检验。结果 ACG、CTA和MRA均能清晰显示外周肺血管及其分支形态学发育情况,CTA和MRA对外周肺血管内径的测量值与手术或ACG实测值相似。结论 CTA、MRA是无创性评估外周肺血管形态学发育情况的良好影像学诊断方法,可以取代有创性ACG检查。Objective To investigate the application of noninvasive imaging diagnosis of peripheral pulmonary vascular anomaly of acyanotic congenital heart disease(CHD).Methods Computed tomography angiography(CTA) and/or magnetic resonance imaging angiography(MRA) were performed on 200 patients with acyanotic CHD and peripheral pulmonary vascular stenosis(36 of whom had postoperative residual peripheral pulmonary vascular stenosis) before operation or angiocardiography(ACG),the diameters of stenotic segment of peripheral pulmonary vessels were measured by CTA and MRA,and were compared with those obtained by ACG or intraoperative direct vision through paired-samples T test.Results ACG,CTA and MRA could clearly demonstrate the morphology of peripheral pulmonary vessels and their branches.There was no significant difference between the diameters of stenotic segment of peripheral pulmonary vessels measured by CTA and MRA and those obtained by ACG or intraoperative direct vision.Conclusion CTA and MRA are favorable noninvasive imaging methods in evaluation of morphology of peripheral pulmonary vessels,and can replace the invasive ACG.
