Abstract:

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.
