This person now knows that they have serious stenosis, but have been told that they will never be able to get it treated now unless a new type of dye is invented.
Ever heard of this? Is there seriously no workaround?
Life threatening contrast (dye) reactions occur with an estimated frequency of 1:140,000 to 1:1,000,000. Prior allergic reactions predisposes to another one. Life threatening reactions include anaphylactic reaction, irreversible asthma or bronchospasm, edema of the throat so bad the airway cannot be secured. It is generally considered an absolute contraindication to further imaging with contrast media.
risk analysis does not favor performing this procedure. While we believe that the liberation procoedure has great potential benefits compared to general risk estimates, in this particular patient risk may out weigh benefit.
the only alternative i can think of is to perform the procedure under IVUS alone. that would be quite a challenge. However, with prior venogram completed, it is not without some merit.
i would only consider it, however, in the group where benefit is most compelling, namely RRMS
