The answers are;
2-Depends on time
i am very thankful that Dr S doesn't agree with number 2. his typical 2 hour routine turned into a 5+ hour marathon because he couldn't fix one thing but wouldn't give up.
total additional cost to patient was $0.
We both have had two procedures because the first one did not investigate the full extend of our CCSVI syndrome (they were early procedures). I do not doubt the there are lots of Interventionalists, like Dr Syed, who are skilled in their profession. However, if they do not use the correct tools (Catheter venography and IVUS) and leading practice, they may miss some problems. Many pwMS do not have the luxury of two or three procedurers. My aim is to point out the 'gold standard' clinics, who are more likely to get it 'right first time'.
my partner's first procedure was in Germany and done in the early evolution of CCSVI. the stage when very little was known about it. IMO, the doctor did a great job given the knowledge and tools at his disposal.
however, giving the knowledge and tools available today, there is no excuse for missing things or undertreating or damage because of too aggressive treatment.
