Limitations
This study includes some notable limitations. Firstly, these results were analyzed retrospectively and evaluated from a single endovascular team which may have established a selection bias. Overall number of the study population was relatively low. Secondly, unfortunately, the cause of late deaths could not be identified for some patients. Therefore, analysis for aneurysm-related death and non-aneurysm-related death could not be constructed for this study. Lastly, considerably short follow-up time may be a limitation to assess the predictors of survival accurately. On the other hand, projection of 5-year survival which is comparable to the literature, satisfactorily assessed by the analyses in this study.
