Duke Surgeons Implant Synthetic Human Vein

My opinion:  This successful surgery is a massive milestone in the medical field.  Without it, I'm not entirely sure that it will be possible to replace organs by using stem cells.  For example, how will these organs be connected to the already existing veins in the body?  Maybe bioengineered veins can fill in the gap.  Furthermore, if one organ is not receiving enough nutrients, doctors could insert a vein to support the organ.  The only worry that I have is that this would take up too much space or take nutrients away from other organs.  But perhaps most importantly, if someone has a history of severe history or bleeding in certain veins, then these may be replaced.  I could see this preventing many strokes (especially reoccurring ones), among other problems!  This is an exciting invention any way you look at it, and I think it represents how far we're at in the surgical industry.  My big question is, what's next after this?  Feel free to comment.

(Medical Xpress)—In a first-of-its-kind operation in the United States, a team of doctors at Duke University Hospital helped create a bioengineered blood vessel and implanted it into the arm of a patient with end-stage kidney disease.
The procedure, the first U.S. clinical trial to test the safety and effectiveness of the bioengineered blood vessel, is a milestone in the field of tissue engineering. The new vein is an off-the-shelf, human cell-based product with no biological properties that would cause .
Using technology developed at Duke and at a spin-off company it started called Humacyte, the vein is engineered by cultivating donated on a tubular to form a vessel. The vessel is then cleansed of the qualities that might trigger an immune response. In pre-, the veins have performed better than other synthetic and animal-based .
