    BackgroundThe selection of different arterial cannulation site influences the incidence of postoperative stroke in patients with DeBakey I acute aortic dissection. The study aimed to explore the optimal arterial cannulation for these patients.MethodsFrom January 2009 to 2019, a total of 1514 patients with DeBakey I acute aortic dissection underwent frozen elephant trunk and total arch replacement at a tertiary center. They were divided into 2 groups: the axillary artery only cannulation group (n = 1075) and the femoral artery cannulation group (n = 439). After balancing the differences of baseline condition by propensity score matching, the prognosis was compared.ResultsThe incidence of stroke and acute brain infarction in the femoral artery cannulation group was higher than in the axillary artery only cannulation group (stroke, 11.7% vs 7.0%, P = .03; acute brain infarction, 6.0% vs 2.7%, P < .01). The femoral artery cannulation group was further divided into 2 groups: femoral artery only cannulation group (n = 106) and axillary combined with femoral artery cannulation group (n = 333). The comparison was performed between the axillary combined with femoral artery cannulation group and the axillary artery only cannulation group. After propensity score matching, the incidence of stroke and acute brain infarction in the axillary combined with femoral artery cannulation group was higher than in the axillary artery only cannulation group (stroke, 13.5% vs 7.2%, P < .01; acute brain infarction, 6.9% vs 2.5%, P < .01).ConclusionsAxillary artery only cannulation is recommended as the optimal arterial cannulation strategy for most patients with DeBakey I acute aortic dissection. For those patients who are not suitable for axillary artery only cannulation, axillary combined with femoral artery cannulation is not recommended.Copyright © 2022 The American Association for Thoracic Surgery.
