My mother had two blockages in her upper right leg removed on Nov 17, with placement of one stent, and she has been on Plavix for past 4 weeks plus. She received lots of IV fluids prior to and after procedure. She is now at home (mom is 82 years old, high blood pressure, 39% kidney function) only current exercise is going to bath room. Last night her right ankle and foot started swelling, and now is quite swollen. We will contact the doctor who did procedure tomorrow, but need to know if there is any immediate concern, and can we do anything other than elevating her foot to help.
