After endovascular repair of abdominal aortic aneurysms, mortality rises over time but doesn’t surpass that associated with open repair, a New England Journal of Medicine study suggests.
From more than 125,000 Medicare beneficiaries who underwent either procedure, about 40,000 in each procedure group were matched according to propensity to undergo endovascular repair. Periprocedural mortality was 1.6% with endovascular repair and 5.2% with open repair. Survival remained significantly better after endovascular repair for 3 years, after which it was essentially the same in both groups. (See Figure 1 at the link below.)
Cumulative mortality in the study population was 50% at 8 years. Late rupture occurred in 5.4% after endovascular repair and 1.4% after open repair.
