# Blunt Traumatic Aortic Injury Treated with Endovascular Aortic Repair: Does Age Influence the Outcome?

## TL;DR

This study examines how age affects outcomes in patients treated for aortic injuries using a minimally invasive procedure, finding that age may not significantly impact results.

## Contribution

The study provides new evidence that age does not significantly influence postoperative outcomes in TEVAR-treated BTAI patients.

## Key findings

- Older patients had worse preoperative health scores but similar postoperative outcomes compared to younger patients.
- Injury severity strongly correlates with ICU stay duration, regardless of age.
- In-hospital mortality was low and not related to aortic complications.

## Abstract

Background: Blunt traumatic aortic injury (BTAI) is the second most common cause of death following blunt trauma, and it can affect people of all ages. The aim of this study was to evaluate age-related differences in outcomes among patients undergoing thoracic endovascular aortic repair (TEVAR) for BTAI. Methods: All patients treated with TEVAR for BTAI at a tertiary care center in Europe between 2005 and 2023 were included in this study. All clinical and imaging data were collected and analyzed retrospectively. Results: A total of 70 patients with a median age of 43 years were included, and 89% were male. Older patients had significantly higher American Society of Anesthesiologists (ASA) physical status classification scores (p < 0.001) compared to younger patients. All age groups (<18, 18–40, 41–65, and >65) exhibited low to borderline low initial hemoglobin levels with a further decline over time (p = 0.063, p < 0.001, p < 0.001, and p = 0.018, respectively). Age groups were comparable regarding injury mechanism, Injury Severity Score (ISS), concomitant injuries and postoperative complications. The age-independent ISS showed a moderate to strong correlation to the length of intensive care unit stay (r = 0.594, p < 0.001). Total in-hospital mortality was 6% and none was from aortic-related complications. There was a generally high rate of loss of follow-up (59%). Conclusions: Although older patients presented worse ASA scores in comparison to younger patients, no significant differences regarding postoperative morbidity/mortality were noted. These findings imply that patient age and preinjury physical status might not substantially influence outcomes when treating BTAI with TEVAR.
