I got my first port, right clavical, in July '10.
Worked flawlessly thru Jan of this year.
Then, at every infusion the nurse were getting a 'poor draw', so they tried the cath-clearing gymnastics and the special flush solution.
Everytime, Feb thru April.
And everytime, they had to draw blood for labs thru an arm IV; no biggie, I have great veins.
And the infusion went IN thru the portacath just fine everytime.
By end of April, the onc took note when I complained, and arranged for a CT scan.
Which showed that the catheter down my carotid vein had coiled all the way back on itself to the point of vein insertion!
The surgeon said this condition isn't unheard of, but most often occurs to large-breasted women for some reason, perhaps sleeping position.
I have slight man-boobs, but nothing that rates a "man-bra'
I do sleep only on my side, often with the lower arm stretched to th headboard. :shrug:
I have a souvenir of the CT screen showing the coil, that I took with my phone camera.
They removed the old port and inserted a new one, which has been fine until now.
At yesterday's infusion, we were again getting a poor draw, but that changed with the gymnastics.
We'll see how this progresses.
Find out from your mum's onc just what the problem is with her port.
So portacaths can fail in some odd ways.
Hope all goes smoothly with her chemo holiday!
