Your question:
can chemo IV reach a point where it is untenable due to complications in administration by vein?
I am not aware of any situation where the lack of vein access prohibited the adminstration of chemo. This is due to better ways to to give the medications via central access.
IV chemo as you describe can only be given intravenously. When the peripheral veins are no longer usable, then as Kerry said, a central line may be inserted. In fact, some chemo cannot be given except by central line due to the damage the chemo causes the veins.
There is a difference in a heart stent if that is what you mean by heart splint and a central IV line for chemo.
A portacath is a central line placed by a surgeon in an outpatient procedure. This central line is "capped" off with a special metal device and can be used when needed. There is no pain after the insertion except for site soreness and is painless when used for chemo. If not in weekly use, the portacath will need to be accessed and flush at least every 30 to 45 days to insure that it reamins patent or open.
