1133 Long Term Survival After Standard EVAR: Have We Started to Treat The EVAR-2 Patient?

Aim Abdominal aortic aneurysm repair was traditionally preformed with open surgical repair (OSR). Recently endovascular aneurysm repair (EVAR) has increased in popularity due to its less invasive nature particularly in those deemed unfit for OSR. The EVAR-2 trial found no significant difference between BMT and EVAR in the 30 days all-cause mortality. This questioned whether EVAR was the best option in those medically unfit for OSR. Method Elective EVAR procedures from the 1st April 2012 to 1st September 2017 were analysed with Kaplan-Meier graphs. The patient data was stratified by year, age group and EVAR risk scoring. Results The all-cause mortality at 30 days was 1.8%, at 6 months it was 7%, and at 4 years it was 19.8%. There was no significant difference with log rank analysis of the year of EVAR operation and consultant (P > 0.05). The log rank analysis found a significant difference between the stratified age groups (P < 0.001) and the EVAR scoring (P = 0.032). At all time-points the RLUH EVAR patients had a lower all-cause mortality compared to the EVAR-2. At the 4-year time point, the RLUH EVAR group had lower all- cause mortality than both EVAR-1 and EVAR-2 trials. Conclusions The retrospective audit data from 2012-2017, suggest the RLUH EVAR treatment practice is not falling into the EVAR-2 trial findings. At all time-points the RLUH EVAR patients had a lower all-cause mortality compared to the EVAR-2. Therefore, it can be concluded the RLUH is not treating EVAR-2 patients.
