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.
