National outcomes for the treatment of ruptured abdominal aortic aneurysm: Comparison of open versus endovascular repairs

Percent of patients with ruptured aortic abdominal aneurysms repaired endovascularly (A), percent of surgeons using endovascular procedures for ruptured aortic abdominal aneurysm repair (B), and percent of hospitals using endovascular repair for ruptured aortic abdominal aneurysm (C) from 2001-2004. P values of trends shown in the parenthesis.

Kaplan-Meier analysis of survival of patients treated with endovascular (EVAR) and open (OAR) repair of ruptured aortic abdominal aneurysm. Cases were matched by patients baseline demographic (age, gender and race), comorbidities, annual hospital and surgeon volume and year of surgery using propensity score analysis.

Thirty-day mortality after ruptured aortic abdominal aneurysm surgery in relation to annual surgeon volume of aortic abdominal aneurysm repair by quintiles: A, open (ruptured and elective), B, endovascular (ruptured and elective), or C, ruptured (open and endovascular). *P <.05 for volume quintiles vs the first quintile.

Kaplan-Meier survival analysis after ruptured aortic abdominal aneurysm surgery by surgeon volume. A - survival after open repair of ruptured abdominal aortic aneurysm in relation to annual surgeon volume of open aortic abdominal aneurysm repair (ruptured and elective) by quintiles. B - survival after endovascular repair of ruptured abdominal aortic aneurysm in relation to annual performing surgeon volume of endovascular aortic abdominal aneurysm repair (ruptured and elective) by quintiles. C - survival after repair of ruptured abdominal aortic aneurysm in relation to annual performing surgeon volume of ruptured aortic abdominal aneurysm repair (open and endovascular) by quintiles.

Thirty-day mortality after ruptured aortic abdominal aneurysm surgery in relation to annual hospital volume of aortic abdominal aneurysm repair by quintiles: A, open (ruptured and elective), B, endovascular (ruptured and elective), or C, ruptured (open and endovascular). *P <.05 for volume quintiles vs the first quintile.

Kaplan-Meier survival analysis after ruptured aortic abdominal aneurysm surgery by hospital volume. A, survival after open repair of ruptured abdominal aortic aneurysm in relation to annual hospital volume of open aortic abdominal aneurysm repair (ruptured and elective) by quintiles. B, survival after endovascular repair of ruptured abdominal aortic aneurysm in relation to annual hospital volume of endovascular aortic abdominal aneurysm repair (ruptured and elective) by quintiles. C, survival after repair of ruptured abdominal aortic aneurysm in relation to annual hospital volume of ruptured aortic abdominal aneurysm repair (open and endovascular) by quintiles.
