8. Are there any risks?

When the catheter is first removed from your arm or groin, you may experience heavy bleeding. This is not unusual, but your doctor will watch carefully to make sure there is no underlying problem. If the catheter has damaged your artery and this problem is the source of your bleeding, you may need surgery to stop the bleeding. Although it is unusual, you could also have an allergic reaction to the dye that the doctor injects into your artery, or to the anesthesia. May doctors will do a medical history to determine the risk of this before the procedure. Finally, there is a risk of developing a blood clot, which is painful at the least or can cause swelling. If a clot travels to the lungs or heart, it can be fatal.
