Abstract
- With the development of devices and techniques, including complex shape coils, balloons, multiple catheter techniques, and intracranial stents, endosaccular treatment of ruptured or unruptured wide-necked cerebral aneurysms has advanced rapidly with respect to indications and outcomes. In contrast to other options, stent-assisted aneurysm embolization has a distinct feature in which the stent is permanently implanted in the cerebral vessels. Therefore, we must consider the short-term effect of stent-assisted aneurysm embolization in the prevention of coil migration and adverse thrombogenicity, but also the permanent mechanical, hemodynamic, and biological influence on the parent vessels and the aneurysm. We have reviewed the current experimental and clinical data on stent-assisted coil embolization of cerebral aneurysms.
