Port needs to be replaced

I have had two ports and will need a third port to complete my chemotherapy.  The first port upon removal have a small slit in the catheter.  The port in at the present has back pressure.  The blood will spurt our when the needle is removed.  Where should the new port be placed?  So far the oncologist and surgeon believe I have had trouble because I'm thin.  My son is quadraplegic and I do provide assistance with transfers and adjusting him in bed.  I do not provide all of the assistance he pushes so I do about a quarter of the work.  The surgeons knows this but I worry  if the next port will fail.

Hi,
A chemoport usually allows some amount of physical exertion. Being thin should not lead to port complications. Do you have any clotting tendency?
It may just be a co-incidence that you have required three ports for your chemo. Most people need just one.
I hope this one gets you through the remaining cycles withour any problem.
All the best, and God Bless!
