Rationale
The integration incorporates a high-quality 2025 meta-analysis (Romijn) which provides evidence for expanding non-operative management to select Grade II injuries, a significant update to standard practice. It also includes the latest clinical practice guidelines (Wagner 2025) and long-term cohort data (Prendes 2026) to reinforce existing recommendations for TEVAR and delayed repair timing. All required abbreviations were expanded on first use within the section.
