Multiple surgeries is not sustainable. Too much uncertainty.

It seems highly failure prone. If you don't block the flow are you going to stroke out?

I'm not sure where this is coming from. Multiple cardiac bypasses have a ton of uncertainty, but they are effective because efficacy is measured by quality of life * increased lifespan.

Multiple surgeries (the time it takes to regrow major veins from capillaries that aren't blocked off) to relatively non-lethal parts of the body seems very sustainable for a human lifespan after 60 or 55 or whatever.
