BACKGROUND: This study aimed to identify differences in prognosis, causes of death, and outcomes between open and endovascular repair for aortic arch aneurysms.
METHODS: We retrospectively analyzed the survival status and causes of death determined from the medical records of 124 consecutive elderly patients (age > 70 years) with aortic arch aneurysms that were treated between 2010 and 2018 at our hospital. Forty patients (male, n = 30; mean age, 76 years) underwent open repair and 84 (male, n = 68; mean age, 78 years) underwent endovascular repair.
RESULTS: Early postoperative complications (10.0% vs. 6.3%; P = 0.4) and rates of in-hospital death (2.5% vs. 6.3%; P = 0.2) did not significantly differ between open and endovascular repair. Cumulative long-term and event free survival rates at eight years were similar in both groups (78.7% vs. 66.3%, P = 0.1 and 66.6% vs. 58.4%; P = 0.4, respectively). The causes of death at follow-up after endovascular repair comprised malignancies in 11 (52.4%) patients and cardiopulmonary and cerebral events unrelated to aortic aneurysms in 10 (47.6%).
CONCLUSIONS: Early and late outcomes did not statistically differ after both procedures. However, the prevalence of cancer-related death occurring late after arch repair was significantly higher after endovascular repair. The most important observation from this series was that significantly more patients died of malignant disease during follow-up after endovascular repair than open repair.
