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

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.

Sun's procedure for Stanford A type aortic dissection through single upperhemisternotomy approach / 中华胸心血管外科杂志

Objective To evaluate the feasibility and safety of Sun's procedure for Stanford A type aortic dissection through single upperhemisternotomy approach ( from the Strernal Notch to the level of fourth intercostal space ) .Methods 58 patients(39 male and 19 female) with Stanford A type aortic dissection were retrospective for this study, who were(46.3 ±9. 5) years old.Sun's prcedure were carried out through single upperhemisternotomy approach and the perioperative characteris-tics were recorded.Results All patients were finished Sun's procedure through single upperhemisternotomy approach, with 5.2％ of mortality(3 patients died postoperation).The time of cardiopulmonary bypass, aortic cross clamp and circulation ar-rest were respectively(181.6 ±25.5)min,(114.2 ±19.8)min and(29.0 ±5.8)min.Non serious adverse event were found after 2 to 15 months follow-up.Conclusion Sun's procedure through single upperhemisternotomy approach was one of the safe and feasible treatment for Stanford A type aortic dissection , which can reduce the operative wound and improve the patients ' satisfactory.
