          Abstract

          Background

          Despite advances in operative repair, ruptured abdominal aortic aneurysm (rAAA) remains associated with high mortality and morbidity rates, especially in elderly patients. The purpose of this study was to evaluate the outcomes of emergency endovascular aneurysm repair (eEVAR), conventional open repair (OPEN), and conservative treatment in elderly patients with rAAA.

          Methods

          We conducted a retrospective study of all rAAA patients treated with OPEN or eEVAR between January 2005 and December 2011 in the vascular surgery department at Amphia Hospital, the Netherlands. The outcome in patients treated for rAAA by eEVAR or OPEN repair was investigated. Special attention was paid to patients who were admitted and did not receive operative intervention due to serious comorbidity, extremely advanced age, or poor physical condition. We calculated the 30-day rAAA-related mortality for all rAAA patients admitted to our hospital.

          Results

          Twelve patients did not receive operative emergency repair due to extreme fragility (mean age 87 years, median time to mortality 27 hours). Twenty-three patients had eEVAR and 82 had OPEN surgery. The 30-day mortality rate in operated patients was 30% (7/23) in the eEVAR group versus 26% (21/82) in the OPEN group ( P=0.64 ). No difference in mortality was noted between eEVAR and OPEN over 5 years of follow-up. There were more cardiac adverse events in the OPEN group (n=25, 31%) than in the eEVAR group (n=2, 9%; P=0.035). Reintervention after discharge was more frequent in patients who received eEVAR (35%) than in patients who had OPEN (6%, P<0.001). Advancing age was associated with increasing mortality (hazard ratio 1.05 [95% confidence interval 1.01–1.09]) per year for patients who received operative repair, with a 67%, 76%, and 100% 5-year mortality rate in the 34 patients aged <70 years, 59 patients aged 70–79 years, and 12 octogenarians, respectively; 30-day rAAA-related mortality was also associated with increasing age (21%, 30%, and 61%, respectively; P=0.008).

          Conclusion

          The 30-day and 5-year mortality in patients who survived rAAA was equal between the treatment options of eEVAR and OPEN. Particularly fragile and very elderly patients did not receive operative repair. The decision to intervene in rAAA should not be made on the basis of patient age alone, but also in relation to comorbidity and patient preference.

              Endovascular aneurysm repair and outcome in patients unfit for open repair of abdominal aortic aneurysm (EVAR trial 2): randomised controlled trial.

              Endovascular aneurysm repair (EVAR) to exclude abdominal aortic aneurysm (AAA) was introduced for patients of poor health status considered unfit for major surgery. We instigated EVAR trial 2 to identify whether EVAR improves survival compared with no intervention in patients unfit for open repair of aortic aneurysm. We did a randomised controlled trial of 338 patients aged 60 years or older who had aneurysms of at least 5.5 cm in diameter and who had been referred to one of 31 hospitals in the UK. We assigned patients to receive either EVAR (n=166) or no intervention (n=172). Our primary endpoint was all-cause mortality, with secondary endpoints of aneurysm-related mortality, health-related quality of life (HRQL), postoperative complications, and hospital costs. Analyses were by intention to treat. 197 patients underwent aneurysm repair (47 assigned no intervention) and 80% of patients adhered to protocol. The 30-day operative mortality in the EVAR group was 9% (13 of 150, 95% CI 5-15) and the no intervention group had a rupture rate of 9.0 per 100 person years (95% CI 6.0-13.5). By end of follow up 142 patients had died, 42 of aneurysm-related factors; overall mortality after 4 years was 64%. There was no significant difference between the EVAR group and the no intervention group for all-cause mortality (hazard ratio 1.21, 95% CI 0.87-1.69, p=0.25). There was no difference in aneurysm-related mortality. The mean hospital costs per patient over 4 years were UK pound sterling 13,632 in the EVAR group and pound sterling 4983 in the no intervention group (mean difference pound sterling 8649, SE 1248), with no difference in HRQL scores. EVAR had a considerable 30-day operative mortality in patients already unfit for open repair of their aneurysm. EVAR did not improve survival over no intervention and was associated with a need for continued surveillance and reinterventions, at substantially increased cost. Ongoing follow-up and improved fitness of these patients is a priority.
