Problems from and questions about contrast dosages, kidney failure.

• I am speaking for my mother, since she cannot speak for herself. She went for a cardiac cath. She was ambulatory. Her lab work showed normal kidney function. During the cath, a stent was placed, she was given massive amounts of ionic dye. Near end of procedure, she had seizures, respiratory failure. After transfer to ICU, she was intubated and became comatose. The next AM labs showed kidney failure. This was a slow death. She had only had one episode of chest pain prior to procedure. I have no idea why the doctor gave the massive doses and she died. What would be your maximum dose of hypaque sodium? Could 613ml cause renal failure, seizures, death?

Is there an alternative to the iodine based dye they inject into a patient prior to an angioplasty?
Michele Cooper, Alpharetta, Georgia, USA, 2 Jul 2001

My mother, 86 years old, has been diagnosed with a blockage in the renal artery which has caused extremely high blood pressure. The doctor wants to perform angioplasty and insert a stent. My mother, however, is allergic to iodine and suffered cardiac arrest about 8 years ago while having a CAT scan performed. The doctor assures us that there are precautions that can be taken to avoid this type of reaction when the angioplasty is done. Are there any statistics or info on this subject that can help us make the right decision.
