Default How to merge special mesh in ICEM CFD?

I am simulating blood flow. The vessel has lots of complex branches. I hope to mesh the branch region with tetra and prism grid near the vessel wall. For the straight vessel region I want to mesh with hexa and o-grid.

I know without prism grid, it is easy to merge tetra and hexa. But when I merge tetra with prism and hexa with o-grid, ICEM CFD reports some errors.

So what to do next? I also wonder what the best grid is to mesh blood vessel?

Thank you.
