Two device related complications happened in two patients. One was stenosis of the true lumen in the descending aorta caused by infolding of the distal end of the stent-graft immediately after its deployment. The other one was a new intima tear at the distal end of the stent-graft caused by full expansion of the stent-graft two years after stent-graft implantation. With the refinement of the device and enrichment of surgeons' experience, such complications could be avoided in the future. Key Words: Aortic dissection; Stent-graft
