颅内动脉瘤是颅内动脉血管由于先天异常或后天损伤等因素导致局部的血管壁损害,在血流动力学负荷和其他因素作用下,逐渐扩张形成的异常膨出。任何年龄均可发病,40—60岁常见,但其发生率存在明显的地域及种族差异。一项经动脉脑血管造影研究提示,亚洲人群中颅内动脉瘤患病率为2.5%~3.0%[1]

 颅内动脉瘤一旦破裂出血,致死致残率极高,其中10%~15%的患者来不及就医直接猝死首次出血病死率高达35%,再次出血病死率则达60%~80%,幸存者亦多有残疾[1]

 颅内动脉瘤栓塞介入治疗是治疗颅内动脉瘤所采用的一种介入手术,在不阻断周围小动脉或缩小主血管的情况下,阻断血流入动脉瘤,使其与正常的血液循环相隔离[2]

 除患有严重动脉硬化或血管痉挛或猝死且无法接受栓塞治疗等的患者之外,血管内弹簧圈栓塞术可治疗所有颅内动脉瘤患者。血管内弹簧圈栓塞术的目的为在不阻挡任何周围小动脉或使主要血管变窄的情况下将动脉瘤与正常血液循环分离。血管内弹簧圈栓塞术所用的器械主要包括栓塞弹簧圈、颅内动脉瘤支架、血管重建装置等[2]

Endovascular Coil Embolization

Endovascular coil embolization can be used to treat all patients with intracranial aneurysms, except for those with severe arteriosclerosis, vasospasm, or in severe emergencies where the patient cannot be treated with embolization. Endovascular coil embolization is intended to separate the aneurysm from normal blood circulation without obstructing any of the peripheral arterioles or narrowing the main vessels. The instruments used for endovascular coil embolization mainly include embolization coils, intracranial aneurysm stents and vascular reconstruction devices [1].
