Evolution in the surgical treatment of intracranial aneurysms is driven by the need to refine and innovate. From an early application of the Hunterian carotid ligation to modern-day sophisticated aneurysm clip designs, progress has been made through dedication and technical maturation of cerebrovascular neurosurgeons to overcome challenges in their practices. The global expansion of endovascular services has challenged the existence of aneurysm surgery, changing the complexity of the aneurysm case mix and volume that are referred for surgical repair. Concepts of how to best treat intracranial aneurysms have evolved over generations and will continue to do so with further technological innovations. As with the evolution of any type of surgery, innovations frequently arise from the criticism of current techniques.
