Aortic arch surgery under mild hypothermic for Standford type A aortic dissection via single upper hemisternotomy approach / 中华胸心血管外科杂志

ABSTRACT

Objective:To evaluate the feasibility and safety of total aortic arch surgery under mild hypothermicvia single upper hemisternotomy approach.Methods:From January 2019 to July 2019, 35 patients(31 male and 4 female) with Stanford A type aortic dissection were diagnosed, who were(43.7±5.7)years old. Aortic arch surgeries were carried out under mild hypothermic via single upper hemisternotomy approach and the perioperative mortality, time of cardiopulmonary bypass(CPB), aortic cross clamp(ACC), circulation arrest(CA) and morbidity of neurological dysfunction were respectively were recorded.Results:All patients were finished aortic arch surgery under mild hypothermic single upper hemisternotomy approach, with 8.6% of mortality(3 patients died perioperation). The time of CPB, ACC and CA were respectively(202±53)min, (128±28)min and(8±3)min. There were 6 cases of transient neurological dysfunction(17.1%) and 1 case of permanent neurological dysfunction(2.9%).Conclusion:Aortic arch surgery under mild hypothermic for Standford A dissectionvia single upper hemisternotomy approach is safe and feasible.
