Hi Simran,
The problem is that it takes a full two years of intensive chelation to remove the iron from the organs, especially the heart. So, whatever plan you make should take into account that you will have to fully comply with this intensive chelation for that period. You're experienced with the picc line. Do you feel that if had been continued for two years that it would have solved the problem? You've also taken oral chelators. Do you feel they both are somewhat effective? A port will make it possible to take desferal 24/7 for as long as you want, but a port does have some drawbacks, including the surgery you mentioned. So, you need to weigh your prior experience and compare how different approaches have worked.
Nomad brought up a possibility you haven't considered, two oral chelators. The doctors in the US who have used this method say it's just as effective as desferal and an oral chelator. Would it be a possibility for you that you take full daily doses of both Asunra and Kelfer? Do they agree with you enough to try it? Your history does justify a different approach, and I wonder if it might be the method that would work for you, since desferal seems to not do enough. Whichever approach you choose, be ready to stay with it for at least two years (unless of course, the choice proves inadequate), so think about what you feel would work best for you in terms of full compliance. Some find a port does that for them, but if oral chelators suit you, it might be the best approach for a long term plan, as long as you have white cells and liver function checked regularly. It's going to take two chelators, so make a judgment based on your experience and go intensive.
