[New surgical approach for acute type A aortic dissection; combining classic surgery with descending stent grafting].

The outcome of surgical repair of acute type A dissection has substantially improved, but patients with residual dissection in the descending aorta are facing a risk of late complications such as aneurysm formation and rupture, and often require redo surgery. To minimize late complications, the combined approach with hemi-arch replacement and simultaneous descending stent grafting (SG) was applied and compared with conventional surgery. Between April 2007 and April 2010, 70 consecutive patients with acute type A dissection underwent operation, and 8 with DeBakey type II and 9 undergoing total-arch replacement were excluded from the study.
