Fig 6. WSS distribution at the distal aneurysm wall and distal vessel wall in straight (S) and curved (C) models before and after stent placement, calculated from CFD simulation (Re = 490). Color scale represents WSS values from <15 dynes/cm² (deep blue) to >35 dynes/cm² (bright red). The impact zone is defined as the area where WSS is >20 dyne/cm², a value considered the upper limit for normal physiologic WSS.
