To determine whether emergent endovascular repair (eEVAR) can be an alternative for anatomically suitable ruptured abdominal aortic aneurysms (RAAA) in a Chinese population compared to open aneurysm repair (OAR), 36 patients with RAAA undergoing either OAR or eEVAR in National Taiwan University Hospital from 2005 to 2012 were analyzed retrospectively. Thirty-five (97.2 %) patients were treated. Among them, 20 (57.1 %) were treated by OAR and 15 (42.9 %) by eEVAR. The overall 30-day survival rate was 77.1 %. There was no significant difference in 30-day mortality rate (OAR 15.0 % vs. eEVAR 33.3 %, p = 0.201) and midterm mortality rate (OAR 20.0 % vs. eEVAR 46.7 %, p = 0.093) between these two groups. On univariate analysis, free peritoneal rupture (p < 0.001), pre-operative shock (p = 0.001) and female gender (p = 0.016) are related to a higher 30-day mortality rate, while free peritoneal rupture (p = 0.012) and pre-operative shock (p = 0.030) are associated with a higher midterm mortality rate in both repair techniques. On multivariate analysis, free peritoneal rupture was associated with higher 30-day (OR 26.0, 95 % CI 2.2-295.6, p = 0.009) and midterm (OR 13.1, 95 % CI 1.2-37.6, p = 0.032) mortality rates. In patients with RAAA, there is no significant difference in 30-day mortality and midterm mortality between eEVAR and OAR groups in our study. eEVAR could be an alternative therapy for anatomically suitable RAAA in a Chinese population.
