Factors causing the formation and growth of intracranial aneurysms include injury and congenital vulnerability of the arterial wall. Therefore, coil embolization of the saccular and fusiform components of intracranial aneurysms is not always curative, and the risk of recurrence in the long-term follow-up is high. Recently, flow diverters(e.g., pipeline, FRED, and Surpass Streamline)and an intrasaccular flow disruptor(W-EB)have been introduced as alternative embolic devices for intracranial aneurysms. These devices can repair arterial walls through neointimal formation surrounding the aneurysm neck and achieve complete cure. The PulseRider is a type of neck bride stent for bifurcation aneurysms that can effectively prevent coil herniation into the parent artery.
导致颅内动脉瘤形成和生长的因素包括动脉壁损伤和先天性易损性。因此，颅内动脉瘤囊状和梭形部分的弹簧圈栓塞并不总是能治愈，长期随访中复发风险很高。最近，血流导向装置（如Pipeline、FRED和Surpass Streamline）和囊内血流干扰装置（W-EB）已被引入作为颅内动脉瘤的替代栓塞装置。这些装置可通过动脉瘤颈部周围的新生内膜形成修复动脉壁并实现完全治愈。PulseRider是一种用于分叉动脉瘤的颈部桥接支架，可有效防止弹簧圈疝入母动脉。
