I have three stents in my iliac veins.since September 2018. Since then my legs from below my ankles and down four inches onto the foot and to about ten inches above the ankle have turned dark brown and are very painful and swollen. It is time to check if the stents are sill in the proper place and are still circulating properly. The cardiologist wants to do a cat scan with contrast. The endochronolgist says no contrast as it will be deadly for me with my problems. What next? Still waiting for cardiologist to figure out what other way can be used to see if the stents are in place and working. (This cardiologist was not the person to put the stents in place.) I think I have made a very poor decision in having the stents placed into my body. (Sometimes we grasp at straws to continue to live.) I feel stupid and shamed at what I have done for to remove the stents at age 82 is a deadly procedure. It is embarrasing to write this but maybe it will help others to think ten times before doing this. Be kind don't yell at me. (Perhaps some one should talk (yell) to the doctor who told me to do this procedure). Anyway still smiling.
