An intracranial aneurysm is an abnormal expansion of the intracranial artery under increased hemodynamic load and other factors caused by local damage of the blood vessel wall due to congenital abnormality or acquired injury. It can occur in people at any age and is common in people aged 40-60, but with significant regional and ethnic differences. The intracranial aneurysm prevalence in the Asian population ranges from 2.5% to 3.0% as shown in a transarterial cerebral angiography study[1].
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[1]。
