Abstract

Abstract: OBJECTIVES: Outcomes of planned and unplanned (rescue) double arterial cannulation (DAC) in surgery for acute type A aortic dissection were investigated retrospectively. METHODS: The study involved 805 patients who were divided into 4 groups according to the cannulation strategy: single cannulation of the femoral artery ( n = 338), axillary artery ( n = 256), left ventricular apex ( n = 52) or ascending aorta ( n = 5) (total, n = 57), and DAC ( n = 154). Patients who underwent DAC were divided between planned ( n = 132) and rescue ( n = 22) usage. Characteristics and outcomes were compared between groups. Both unmatched and propensity score-matched analyses were performed. RESULTS: Shock (39%, 19%, 33% and 14%, in the femoral artery, axillary artery, left ventricular apex/ascending aorta and DAC, respectively) and leg malperfusion (5%, 16%, 16% and 26%, respectively) differed significantly ( P < 0.001), but in-hospital mortality did not (9%, 8%, 18% and 7%, respectively; P = 0.096). The 5-year survival rates were 79.4%, 79.7%, 78.6% and 82.2%, respectively. Propensity score-matched analysis showed no statistically significant differences in in-hospital mortality rates (10%, 12%, 14% and 9%, respectively; P = 0.78) and 5-year survival rates (78.4%, 72.3%, 82.3% and 78.0%, respectively). The leading vessel combination and indications for planned and rescue DAC were the femoral and axillary arteries (98%) and true lumen narrowing and/or leg malperfusion (34%), and the axillary followed by femoral (77%) artery and low cardiopulmonary bypass flow (36%). In-hospital mortality in the planned and rescue DAC groups was 7% and 9%, respectively. CONCLUSIONS: DAC seems effective for both prevention and management of intraoperative malperfusion.
