Hello,

I’m interested in seeing if any of my colleagues at other facilities have been experiencing an increase in adverse events associated with the use of IV contrast in neurointerventional endovascular procedures.

To summarize briefly, we have recently observed an increase in events where these patients have experienced symptoms of stroke, seizure and encephalopathy post neurointerventional procedures with subsequent recovery. One common feature among these patients is the unexpected presence of IV contrast in the brain post procedure.
