血流导向装置治疗颅内大型或巨大型动脉瘤的研究进展

随着神经介入技术、材料学、计算机模拟技术的发展，以及血流导向装置的产生，新技 术新材料使得颅内大型或巨大型动脉瘤的治疗方向发生了转变，由既往针对动脉瘤的治疗转变成重 建载瘤动脉血流。目前国内外临床上已应用多种血流导向装置，其安全性和有效性已得到证实。本 文主要对颅内大型或巨大型动脉瘤的临床特点，血流导向装置治疗未破裂颅内大型或巨大型动脉瘤 的作用机理、临床应用现状及其并发症进行了综述。

Progress of Flow Diverter Devices in Treatment of Large or Giant Intracranial Aneurysms

With the development of neurointervention techniques, material science and computer simulation technology, and the application of new generation of flow diverter (FD) devices, these new techniques and materials have changed the direction of treatment for large or giant intracranial aneurysms (LIA/GIA) from the previous treatment for aneurysms to the reconstruction of parent artery. At present, a variety of flow diverter devices have been applied in clinical practice at home and abroad, and their safety and effectiveness have been proved. This article mainly reviewed the clinical feature of LIA or GIA, the mechanism of FD in the treatment of LIA or GIA, current status of clinical application and complications of FD therapy.
