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.
