Many different techniques for different types of stroke:
We can block certain arteries mechanically by inserting a tool, inject photosensitive agent then cause a targeted clot with a laser, inject clotting agent, choke, inject blood vessel dissolving agent and re-inject its own blood.
I understand why we research this but I just could not do it.
I can understand.
One of our family friends just could not continue draining monkeys of blood for biochemistry research. I have been to his lab. The monkeys would panic whenever their cages were touched.
I can one needs a level of sociopathy or psychopath to continue this kind of research.
The benefits to humanity is substantial though.
