Is it ok for a 90 year old to get a leg angioplasty or is it too risky?

Talk to ur doc: Certainly can be done. Risk depends a lot on how healthy you r otherwise. Certain other chronic diseases can make procedure more risky (kidney disease, diabetes, overall severity of vascular disease) as can complexity of procedure. All these issues must be taken into account to help you assess the risk of the angioplasty. Good luck.

Kidney function?: Age is irrelevant. People who are 20 don't need leg angioplasties - it's done in older folks. His/Her kidney function is critically important. If it's normal and they have no evidence of unstable heart function, it's reasonable to do it to save the leg and/or reduce pain.
