Title: How is arterial anastomosis performed?
Post by: scientizscht on 18/05/2019 17:51:29: Hi

I cannot understand some things about arterial anastomosis eg in coronary bypass.

How is the incision done on the aorta while blood is flowing under high pressure?

How are the vascular grafts attatched?

Thanks

Aren't you going to kill the patient if you clamp their aorta or coronary artery?

Not if you are quick.
