Cardiovascular versus Open Repair of Abdominal Aortic Aneurysm
The United Kingdom EVAR Trial Investigators
From 1999 through 2004 at 37 hospitals in the United Kingdom, involving 1252 patients with large abdominal aortic aneurysms (≥5.5 cm in diameter) to undergo either endovascular or open repair; 626 patients for each group.
Follow up 5-10 years.
30-day operative mortality was 1.8% in the endovascular-repair group and 4.3% in the open-repair group
benefit was lost by the end of the study, at least partially because of fatal endograft ruptures.
end of follow-up, there was no significant difference between the two groups in the rate of death from any cause.
CONCLUCION:patients who were considered to be suitable candidates for either endovascular repair or open repair of abdominal aortic aneurysm, the endovascular procedure was associated with a significantly lower operative mortality. However, no significant differences were seen in total mortality or aneurysm-related mortality in the long term. Endovascular repair was associated with increased rates of complications and reinterventions and was more costly
