Will There Be Any Effects From Tying Of The Blood Vessel During Surgery?

My daughter just had a Baby..The Baby was born just fine but after the baby came ..My Daughter was just gushing blood..They decided to go in and possibly have to do a Hysterectomy if they could not stop the bleeding. They could not fine it until they removed the Uterus . I was hiding the large blood vessel. It was so large they had to tie it off.
What I want to know is will there be any health effects from tying off this vessel and what function did it serve?
The Doctor said in her 19 yrs. of service she had never seen this ??
