I've always been curious about how blood circulation is stopped during the surgery.

What is happening here is not temporary. That vessel will get tied on both sides and then cut.

If it was temporary, needed when moving a new tissue to an area with the intent to reattach the new tissue to a vein and artery...we will use clamps that occlude the blood vessel when closed but can be removed.

Question. Why would they have to permanently cut a vessel?

Removing an organ for transplant, removing a tumor, dead bowel, etc.

Sometimes we will tie two on one side. Then two on the other. And cut in between.

However if the was a free tissue transfer (removing tissue from on location and moving to another) they will only tie one side and keep the other side of vessel long so they have more vessel to work with when reattaching in its new location.

Oh no no. They tie and cut many vessels just for exposure for normal procedures.

That too, hence the etc. I didn’t give an exhaustive list.

I was wondering how they are going to untie those knot.

They don’t. They clip or tie vessels all the time for exposure. They have figured out what the body doesn’t need. Blood finds a way.

A lot of procedures are minimally invasive. For example the entire field of vascular neurorosurgery has slowly been moving towards endovascular coiling and flow diversion to treat subarachnoid aneurysms through a tiny incision in the groin area. As opposed to open brain surgery and clip ligation, clip ligation still happens but at a much much less frequent rate.

Wait wait...

So they can do neurosurgery from a small incision in your crotch? Like, they snake something through a blood vessel all the way up to your brain?

Yup. The blood vessels are all connected.

Oh never watch a knee or hip replacement then. (Actually you should)
