Background
The type “A” aortic dissection (AAD) is a dangerous acute complication of the Marfan syndrome. Not only the native outcome of the AAD is life threatening, but even the surgical treatment of this complication is risky. Despite the improving surgical experience and the more effective cerebral and myocardial protection the lethality of the surgical treatment of AAD at Marfan patients is still high as 10-15 percent. Out of this reasons all the possible medical efforts should be taken to prevent the occurrence of this complication.
