随着影像技术的发展,越来越多的未破裂颅内动脉瘤得到诊断。未破裂颅内动脉瘤每年的破裂率在1%～2%之间,不同研究结果报道影响未破裂动脉瘤破裂的因素各异,包括动脉瘤的大小、位置、形状等等。对于未破裂颅内动脉瘤治疗方案的选择,特别是某些小的未破裂颅内动脉瘤是否可以观察,仍存在很大争议。开颅手术夹闭和血管内栓塞治疗均各有利弊,选择一种合适的治疗方案是一个相当复杂的过程,需要考虑到患者本身及动脉瘤的特点,还要考虑到设备技术,以及医师经验和技术等诸多复杂因素。 With the development of imaging technology, more and more unruptured intracranial aneurysms have been diagnosed. Unruptured intracranial aneurysms rupture rate of 1% to 2% per year, different studies report the impact of unruptured aneurysm rupture of various factors, including aneurysm size, location, shape and so on. There is still considerable controversy regarding the choice of treatment for unruptured intracranial aneurysms, and in particular, whether certain small, unruptured intracranial aneurysms are observable. Craniotomy and endovascular embolization have their own advantages and disadvantages, choose a suitable treatment is a very complex process, taking into account the characteristics of the patient itself and aneurysm, but also taking into account the equipment technology, and physician experience And technology and many other complicated factors.
