Japanese single-center experience of abdominal aortic aneurysm repair over 20 years: should open or endovascular aneurysm repair be performed first?

  Fig. 1. A Receiver operating characteristic (ROC) curve for the propensity score-matched analysis. The area under the ROC curve (AUC) was 0.72. B Violin plots of the matched and unmatched groups as well as the groups before matching showed the distribution of dots based on the logit scale of the propensity score. The distribution of dots in the matched OAR groups was very similar to that of the matched EVAR groups

• 

  Fig. 2. Number of AAA cases. AAA was treated with OAR first strategy from 1999 to 2009. EVAR was introduced in 2008, and OAR first strategy was changed to EVAR first strategy in 2012. After 2018, the EVAR first strategy was changed to the OAR first strategy based on the characteristics of each individual patient

  Fig. 3. The overall survival was significantly better in the OAR group than in the EVAR group in the total cohort. (A) Curves for the overall cohort. (B) Curves of the propensity score-matched cohort

  Fig. 4. In terms of freedom from AAA-related death, there were no significant differences between the OAR and EVAR groups. (A) Curves for the overall cohort. (B) Curves of the propensity score-matched cohort

• 

  Fig. 5. The rate of freedom from aortic events was significantly higher in the OAR group than in the EVAR group. (A) Curves for the overall cohort. (B) Curves of the propensity score-matched cohort

  Fig. 6. The rate of freedom from re-intervention was significantly higher in the IFU group than in the non-IFU group. However, the advantage inherent to the inside IFU group disappeared about eight years after EVAR

  Fig. 7. No significant improvement in freedom from re-intervention after EVAR was detected among the early, middle, and late terms
