My patient has a new porta cath placed 3 weeks ago for vanc infusions. The order is to change huber needle every 3 days. I attempted to access porta cath and I get a beautiful blood return, however, when I flush the site begins to rise significantly. I have been unable to access this. Patient was sent to radiology for a study. He was told he had a hematoma and was sent home with a new access in place. Could the issue I had be due to my technique or a complication with his port??
