We can, and it's been doable (and increasing common) since the early-mid 00s. 

However, as the shape becomes complex 2d approximations become less useful, and given the modern compute power the 3d model is relatively quick. There are also very significant 3d effects in the flows at the bifurcations. If you use the Materialise Mimics/Magics or Synopys Simpleware tools into Fluent Meshing the time to build the models is relatively quick especially for the aorta as it's a fairly straight pipe.
