Our study indicates that stent-assisted coil embolization of intracranial aneurysm is a safe technique with low morbidity and mortality rates. Our results are consistent with those reported in the literature (Table 5). The main cause of morbidity and mortality is thromboembolism (38.2% of all procedure-related complications are thromboembolic in our study). In our hand, this technique does not increase the risk of symptomatic vasospasm, compared with open clipping and other endovascular techniques. The recanalization rate is relatively low. The delayed in-stent stenosis seems a rare complication, compared to stent deployment in atherosclerotic lesions. Nevertheless, additional, large series with long-term follow-up are necessary to determine the durability
