目的:探讨采用单一胸骨上段小切口在浅低温下行Stanford A型主动脉夹层全主动脉弓置换术的可行性与安全性。方法:2019年1月至2019年7月共35例确诊为Stanford A型主动脉夹层患者，其中男31例，女4例；年龄(43.7±5.7)岁。经单一胸骨上段小切口在浅低温下行全主动脉弓置换术并记录围手术期死亡比例、体外循环时间、主动脉阻断时间、停循环时间和神经系统并发症发病率等。结果:全组患者均在单一胸骨上段小切口浅低温下完成手术，围手术期死亡3例(8.6%)；体外循环(202±53)min,主动脉阻断(128±28)min，停循环(8± 3)min。短暂神经功能障碍6例(17.1%)，永久性神经功能障碍1例(2.9%)。结论:单一胸骨上段小切口浅低温下行Stanford A型夹层主动脉弓置换术安全、可行。“,”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.
