主动脉窦部改良三明治修复技术在急性Stanford A型主动脉夹层中的研究进展

Research progress on aortic root repair by modified sandwich technique for acute Stanford type A aortic dissection

急性Stanford A型主动脉夹层起病急、病情重、死亡率高,一旦诊断明确,需要急诊手术治疗。累及窦部的夹层是外科手术的难点,也是导致患者死亡的重要危险因素。提高窦部外科处理水平是提高疗效的关键。本文主要介绍改良三明治技术在急性Stanford A型主动脉夹层中的应用及其预后,总结不同改良三明治技术在主动脉窦部的处理经验。然而,目前对于主动脉窦部的处理仍无统一标准,且上述多种技术缺乏大型长期随访研究,因此需要进一步在实践中改进主动脉窦部处理技术。

Acute Stanford type A aortic dissection has the characteristics of acute onset,severe condition and high mortality.Once making a definite diagnosis,surgical treatment is needed as soon as possible.It is difficult for cardiac surgeons to treat the acute aortic dissection involving the aortic sinus,which is an important risk factor for death.Improving the surgical treatment for the aortic sinus can be a key to improving the prognosis.In this review,we will introduce the modified sandwich technique for acute Stanford type A aortic dissection and the prognosis,and summarize the experiences of different modified sandwich techniques.However,there is still no unified standardized technique in aortic root repair,and there is a lack of large studies with long-term follow-up,so it is necessary to further improve the aortic root repair techniques.
