Abstract

In the last ten years, the endovascular approach to the management of cerebral aneurysms has gone from being an alternative to surgery to being the first-choice technique in the vast majority of cases. The continuous development of new assisted techniques and of new materials for embolization has multiplied its therapeutic possibilities, so that safe and efficacious endovascular treatment is now possible for aneurysms that would have required surgery only a few years ago. These continuous technological advances require the professionals who treat patients with cerebral aneurysms to achieve a high degree of specialization and to keep up to date through continuous training. In this article, we review some of the most widely used assisted techniques in the endovascular treatment of cerebral aneurysms, discussing their main indications, their advantages over conventional embolization techniques, and their possible limitations.

Keywords:
Intracranial aneurysm
Therapeutic embolization
Endovascular procedures
Neuroradiology
Resumen

A lo largo de los últimos 10 años, el abordaje endovascular de los aneurismas cerebrales ha pasado de ser una alternativa a la cirugía a convertirse en la terapia de elección en la inmensa mayoría de los casos. El constante desarrollo de técnicas asistidas y de nuevos materiales de embolización ha multiplicado sus posibilidades terapéuticas, de modo que en la actualidad es posible tratar con eficacia y seguridad aneurismas que hace tan solo unos años hubiesen sido considerados quirúrgicos. Este continuo avance tecnológico exige a los profesionales implicados en el tratamiento de pacientes con aneurismas cerebrales un alto grado de especialización y una actualización formativa permanente. En el presente trabajo repasamos algunas de las técnicas asistidas más empleadas en la actualidad para el tratamiento endovascular de los aneurismas cerebrales, mostramos sus principales indicaciones, las mejoras que suponen respecto a las técnicas de embolización convencional y sus posibles limitaciones.
