Neovascularization v. Angiogenesis?

Question

Anybody know what the difference between neovascularization and angiogenesis is? Thanks for your help!

Answer 1

Neovascularization is the formation of new blood vessels basically from scratch. Angiogenesis is when the blood vessels sprout from pre-existing blood vessels.

Answer 2

There is some degree of overlap b/wn the two; I suppose that neovascularization implies that there is some sort of underlying "regrowth," whereas angiogenesis is a more generic term.

In the context of an endovascular stent, I prefer to use the term neovascularization as I feel it is more precise.

I would check the definition in Stedman's for a more precise answer.
