While still taking Plavix, I had the misfortune of developing a bowel obstruction which required emergency
surgery. The fact that I was was taking
Plavix was a major concern, and the surgery took place expecting bleeding problems. Some bleeding did take place but they were prepared for it and I got through it OK. As Kenkeith suggests, when I had planned medical procedures when taking Plavix, I just quit taking it a week ahead of the planned procedures.
