My husband had 2 stents put in his arteries once and then about 2 years later he had to have 2 more but each time they had to cut and go through the main artery in the groin. He had a huge tube in the artery that had to stay there for at least 12 hours so he had to stay in the hospital for at least 48 hours. They said he had to stay flat on his back because he would start bleeding and would bleed out fast. I remember it so well. The second 2 stents were put in September 11, 2001. He was in surgery when the planes hit the WTC.
They used a thing on me that stops the bleeding and you don’t have to be still for 12 hours. At another hospital I know of a man who went through what your husband went through. Depends on the hospital, I guess.
