Octogenarians face higher risk after complex AAA repair, Portuguese registry finds

A multicentre observational study using the Portuguese National Registry of Vascular Procedures examined outcomes of complex abdominal aortic aneurysm repair in 418 patients, 21.5% of whom were aged 80 or older. The study reported that octogenarians were more often treated endovascularly, with fenestrated/branched EVAR emerging as the preferred technique by 2024, but had significantly higher 30-day major adverse events (21.1% vs 14.0%), 30-day mortality (8.9% vs 3.0%), lower textbook outcomes, and lower one-year survival (65.2% vs 88.2%) compared to younger patients. The authors state these findings raise concerns about patient selection and expected benefit of complex AAA repair in elderly patients.

Most relevant for: Patients aged 80 years or older being considered for complex abdominal aortic aneurysm repair involving the renovisceral segment.
