Malposition after power injection

[DAVID LONGSETH]

Saw a set of CXR's last week that were of interest. Pt had a 5Fr Power PICC 
placed in the AM,then a CT in the afternoon (chest for PE,I think). Later in 
the evening pt. began having discomfort and swelling in the neck. CXR after 
PICC placed showed a good lower SVC placement but the evening's film showed 
the line up the IJ,perhaps with the tip in smaller collateral vein. 
Apparently the CT contrast injection was strong enough to flip the PICC up 
there.
Was wondering if anyone else has seen this occur,but then also wonder if 
this doesn't happen more frequently and we just never know....
