Abstract：To investigate the effect of aortic root plasty by intimal flap exclusion on Standford type-A dissection. Methods The patients with Standford type-A dissection (n=13) were chosen into study group, and patients received modified "sandwich" proximal aortic root plasty (n=13) were chosen into control group from Department of Cardiac Surgery of Zhengzhou Municipal Seventh People’s Hospital from June 2015 to July 2017. All patients were given relative examinations before admission, and underwent aortic root plasty by intimal flap exclusion after hospitalization. The levels of left ventricular end-diastolic inner diameter (LVEDd), left ventricular end-systolic diameter (LVESd) and left ventricular ejection fraction (LVEF) were detected by using color echocardiography before and after the operation. The patients were followed up for from 7 months to 17 months, and degree of aortic regurgitation was recorded. The application effect of aortic root plasty by intimal flap exclusion was analyzed in treatment of Standford type-A dissection. Results The operation was success in study group, and time of cardiopulmonary bypass (182.31±23.85) min, time of aorta blocking (132.94±30.85) min, blood transfusion volume (1020.31±36.93) m L and length of hospital stay (9.32±1.46) d were all higher in control group than those in study group (P<0.05). The levels of LVEDd (51.23±5.06) mm and LVESd (41.23±5.93) mm were all lower in study group than those in control group (P<0.05). The level of LVEF was (53.31±4.98)% in study group, which was significantly higher than that in control group (P<0.05). The incidence of postoperation non-aortic regurgitation was higher in study group than that in control group (P<0.05). The incidences of mild, little and medium volume of aortic regurgitation were lower in study group than those in control group (P<0.05). Conclusion The efficacy of aortic root plasty by intimal flap exclusion is ideal in patients with Standford type-A dissection, and it is good for improve patients’ heart function, reduce regurgitation degree and worth to be popularized and applied.
