Low blood pressure after AAA surgery: hidden risks revealed
NCT ID NCT07511101
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 511 patients who had surgery to repair an abdominal aortic aneurysm (a bulging blood vessel in the belly) to find out what makes some people develop dangerously low blood pressure after the operation. The researchers reviewed medical records from 2013 to 2021 at a single hospital. They hope to identify risk factors that could help doctors prevent complications and improve survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could help doctors identify patients at higher risk for dangerous low blood pressure after AAA repair and improve their care.
- What could go wrong
- This is an observational study that only looks back at past data, so it cannot prove cause and effect. The findings may not apply to other hospitals or newer surgical techniques.

Inclusion Criteria: * Age \> 18 years * Elective AAA repair between 2013 and 2022 (endovascular and open) Exclusion Criteria: * Data from the blood pressure monitoring system were only available from 2013, so patients treated before January 1th 2013 were excluded. * Patients were also excluded from the study if registered objection to use their data for research, * absence of blood pressure data, * revision surgery after previous endovascular or open repair, * ruptured aneurysm, * mycotic aneurysm, or * treatment with endovascular aneurysm sealing.
