Ten Years of Urgent Care of Ruptured Abdominal Aortic Aneurysms in a High-Volume-Center

The urgent treatment of ruptured abdominal aortic aneurysms (rAAA) remains a challenging condition with devastating morbidity and mortality. Available studies are often limited due to a significant selection bias. This study aims to illuminate real-world evidence using comprehensive data from electronic health records, registries, postmortem findings, and administrative data on all consecutively treated patients presenting with rAAA at a tertiary care center. This is a retrospective cross-sectional cohort study covering consecutively treated patients with rAAA between 2009 and 2018. All noninvasive treatments, fatalities, and invasive repairs were included. Information on patient’s characteristics, prehospital, and inpatient care was gathered. Short-term outcomes and long-term survival were analyzed for relevant subgroups. In total, 139 patients with rAAA (median age 75 years and 20.9% females, 79.9% infrarenal) were treated increasingly frequent by endovascular aortic repair (EVAR) when compared to open-surgical aortic repair (OSR) during the study period (16.7% in 2009 to 33.3% in 2018, P
