Evolution of Endovascular Therapy for Aneurysm Treatment
The endovascular treatment of intracranial aneurysms has recently become an established therapeutic option. The foundation of this treatment modality was laid by the work done in ground-breaking cases, combined with technological advances since the first half of the 19th century. In this historical overview the authors describe the steps taken by the early pioneers and the results of their work, which was often done under challenging circumstances. The work of these predecessors established the stepping-stones for constant development and refinement for those who have come after them, eventually evolving into the procedures used today. Endovascular treatment of intracranial aneurysms is only possible because of the work of these innovators.

The management of intracranial aneurysms has changed dramatically through time. The science and the art involved have advanced tremendously from its early stages, resulting in ever-improving therapeutic options. Like many advances in medicine and science, the evolution of endovascular therapy to treat intracranial aneurysms is the result of a ceaseless process. Many of the concepts applied to aneurysm treatment today have been around for quite some time. Nevertheless, their safe and widespread clinical application has become possible only in the last few decades, with incredible progress being made in the safety and efficacy of the devices available, better imaging modalities, and improved knowledge of the underlying disease process. Some of the most important steps in this process are summarized in this review.
