Device complications in aortic dissection stenting warrant clinical vigilance; leaves open need for device refinement and prospective safety data.
Open stent-graft has been used in the treatment of aortic dissection in recent years. 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.
