Hi, Thanks for writing in. I am a qualified and certified cardiologist. I read your mail. I am sorry but accidental blockade and injury to the main artery of leg is known is a known complication and doctor damaged is not an accurate statement. Femoral artery got blocked as a complication of the PTCA procedure is the correct description. After surgical repair if there is residual problem usually angiography of the leg artery and its branches is carried out and doctor act and advise taking these findings into consideration. I suggest to you to have a word with the your doctor and ask that what exactly is the problem for your question is not clear on the residual damage issue. Please, understand, no doctor wishes any complication to occur in his/her patients and willing to help out. Confrontation of the problem should be priority and confrontation of doctors can take secondary place if needed at all. I do not think any cardiologist have much experience with chelation therapy. Good Luck. With Best Wishes Dr Anil Grover
