CHICAGO – Numerous studies have shown conflicting results for endovascular repair in ruptured abdominal aortic aneurysms (AAA), but an analysis of 4,000-plus cases from a national registry has found a 41% reduction in mortality with endovascular repair vs. open repair, according to a presentation at the annual meeting of the Midwestern Vascular Surgery Society.
“EVAR is becoming an increasingly popular strategy for treatment of AAA,” said Samer Alharthi, MD, MPH, of the University of Toledo in Ohio. “As surgeon experience and endovascular technology have improved, a greater percentage of ruptured AAA are being treated by EVAR.”
Dr. Alharthi reported on a retrospective analysis of 4,133 patients who had repair for ruptured AAA in the American College of Surgeons National Surgical Quality Improvement Program database from 2010 to 2016. Notably, the number of EVAR repairs continue to increase and peaked in 2015, with 53% of ruptured AAA treated by EVAR.
Over the term of the study, the overall mortality rate was 22.6% for EVAR and 33.2% for open repair (P less than .001), Dr. Alharthi said. “After adjusting for cofounders, there was a 41% reduction in the mortality rate with the EVAR approach,” he said.
The only appreciable significant difference in demographics between the two groups was a higher percentage of smokers with chronic obstructive pulmonary disease having open repair – 942 (49.2%) vs. 701 (36.2%) – and a higher percentage of patients with end-stage renal disease having EVAR, Dr. Alharthi said. Other comorbidities had no statistically significant difference.
“Complications – pneumonia, reintubation, and acute renal failure – were higher in the open than the EVAR group,” he said. For example, rates of acute renal failure were 15.4% and 8.2% (P less than.001), respectively. Rates of myocardial infarction were similar between the two groups: 6.3% and 6% (P = .74), respectively.
Dr. Alharthi had no financial relationships to disclose.
