Endovascular Coil Embolization of Very Small Intracranial Aneurysms

ABSTRACT

OBJECTIVE: We aimed to evaluate the results of endovascular coil embolization for very small aneurysms ( or = 4), with no bleeding of the treated aneurysms during a mean follow-up period of 13.3 months. On 27 follow-up MRA, there was no recurrence, and the five incompletely occluded aneurysms showed a spontaneous amelioration resulting in an adequate occlusion. CONCLUSION: Coil embolization of very small aneurysms is technically feasible with good results. The long-term efficacy and the potential as a standard treatment strategy remain to be determined by randomized large trials.
