摘要:
主动脉缩窄是指胸主动脉降段一定程度狭窄,是儿童较常见的先天性心脏病。现有多种诊断标准均基于计算影像学上主动脉不同层面直径之间的比例关系评估主动脉缩窄,不能充分反映主动脉血流动力学状态,不利于制定最佳的个体化手术方案。心导管测压虽然可以充分反映主动脉整体血流动力变化,但是一种侵入性检查,不作为临床首选,因此临床亟需一种无创方式可视化评估患儿复杂的血流动力学变化。近年来,基于影像学资料的计算流体力学通过医工结合的方法计算血管的血流动力学指标,在成人血管性疾病中已崭露头角,有望为主动脉缩窄的诊断及治疗提供一种准确且无创的评价方法。本文将阐述基于影像的计算流体力学在主动脉缩窄无创评估中的研究进展。
Abstract:
Aortic coarctation (CoA) refers to a narrowing of descending thoracic aorta.Various existing diagnostic parameters have indicated that single geometric phenomena such as morphological diameter or proportion fails to reflect the full view of aorta and formulate an optimal surgical plan.Although cardiac catheterization may reflect the overall hemodynamic changes of aorta,such an invasive mode is not a first clinical choice.A non-invasive mode of visually evaluating complex hemodynamic changes is urgently needed.In recent years,computational fluid dynamics (CFD) has been widely applied in vascular diseases for its highly accurate and non-invasive hemodynamic evaluation based upon medical and engineering integration.Thus it is suitable for the severity assessment and treatment guidance of CoA.Here the latest researches of CFD in CoA was summarized along with other imaging studies in CoA.
