Study design
This retrospective cohort study analyzed consecutive patients who underwent emergency surgical repair for AAD at Aichi Medical University Hospital from January 2017 to December 2019. Data were selected retrospectively from the institutional database for aortic disease.
Early and late clinical outcomes were assessed. Early outcomes included early mortality, cause of death, and mesenteric, cerebral, cardiac, respiratory, and renal complications. Late outcomes included late mortality, cause of death, major adverse aortic events (MAAE), and major adverse cardiac or cerebrovascular events. Mesenteric complication was a composite of mesenteric ischemic events and mesenteric reinterventions. Mesenteric ischemic events included paralytic ileus that needed fasting or intestine or colon resection. Mesenteric reinterventions included additional IVR or open revascularization for mesenteric ischemia. MAAE was a composite of either major aortic events or major aortic reinterventions. Major aortic events included rupture or re-dissection of the aorta. Major aortic reinterventions included additional thoracic endovascular aortic repair or a major surgical graft revision.
All procedures were performed in accordance with the Helsinki Declaration. The study was approved by the Ethics Committee of Aichi Medical University Hospital. All patients provided written consent that their clinical data might be used for scientific presentations or publications when they consulted the hospitals for the first time.
