There are multiple blood vessels and multiple connections (anastamoses) between those blood vessels serving each part of the body. Even if you take out a blood vessel, there are still many other "routes" by which blood can get where it is going.
My wife wants to point out that if you take out a main blood vessel, like the aorta for example, you will die. She just loves disagreeing with me.

This can be done because the blood vessel that's moved is a VEIN, not an artery. Generally, arteries are critical-you remove or plug one and some part of you dies. Veins, however, aren't really all that important-they carry blood back to the heart and if you cut one out, the blood will just find another way back. Usually MD's remove veins from the leg with little side-effects.

because of the collateral (alternative) blood vessels , usually done for veins not artries

Collateral circulation exists for Arteries and Veins.
