Yttrium-90 radioembolization (RE) is a widely used transcatheter intraarterial therapy for patients with unresectable liver cancer. In the last decade, computer simulations of hepatic artery hemodynamics during RE have been performed with the aim of better understanding and improving the therapy. In this review, we introduce the concept of computational fluid dynamics (CFD) modeling with a clinical perspective and we review the CFD models used to study RE from the fluid mechanics point of view. Finally, we show what CFD simulations have taught us about the hemodynamics during RE, the current capabilities of CFD simulations of RE, and we suggest some future perspectives.

钇90放射栓塞术（RE）是一种广泛用于无法切除的肝癌患者的经导管动脉内治疗。在过去十年中，为了更好地理解和改进治疗，已经对 RE 期间的肝动脉血流动力学进行了计算机模拟。在这篇综述中，我们从临床角度介绍了计算流体动力学 (CFD) 建模的概念，并从流体力学的角度回顾了用于研究 RE 的 CFD 模型。最后，我们展示了 CFD 模拟教会了我们关于 RE 期间的血流动力学、RE 的 CFD 模拟的当前能力，并提出了一些未来展望。
