Purpose:
The aim of this study was to analyze midterm results of frozen elephant trunk technique for Marfan syndrome with acute aortic dissection.
Methods:
Between February 1999 and August 2011 we performed arch replacement uisng frozen elephant trunk technique for acute aortic dissection in 8 patients with Marfan syndrome containing two complicated type B dissections and six type A dissections.Five patients compromised annulo-aortic ectasia who performed Bentall operation.
Results:
No patients died in the initial operation. Fate of false lumen on the stent graft border was expressed by CT scan follow-up that were patent in 0, thrombosis in 5 and absorption in 3 patients. One patient who had new aortic dissection 8 years after initial surgery required the Crawford V operation. Ten-years-survival rate was 100% and ten years-event free rate was 67%.
Conclusions:
Frozen elephant trunk technique was feasible for Marfan syndrome with acute aortic dissection and might become alternative prophylactic treatment to the downstream aorta for acute aortic dissection.
