Posterior circulation aneurysm is difficult to treat because surgical approach is time consuming procedure and the risk of postoperative morbidity is still high due to the infarction as the result of the vascular injuries and direct injury to the brain stem and low cranial nerves. Endovascular occlusion is another treatment option for these aneurysms because the postoperative mortality and morbidity are lower than the direct neck clipping. Recently, treatment strategy is advanced, like combined treatment, emergency endovascular occlusion of the sac and direct neck clipping when the patient condition improves or vise versa. Technical and material developments are also noted, balloon assisted neck plasty, stent with coil are also available and 3D coil is recently innovated. Our 3 year experiences of endovascular treatment for posterior circulation aneurysms will be presented. More long-term follow-up is necessary to evaluate the final results, but technological development can reduce the procedure-related complications and newly designed coil and catheters can improve the results and more patients will be helped by this method.
