I had a picc line. PICCs are for more short term use, I had mine for 6 months though. Mine had 2 lines hanging out of my arm. You maintain it just like you would a port if the port is accessed. You still flush and heparinize it daily, clean the site weekly with a sterile kit. I instructed my husband on how to do this for me since I use to be a nurse. The big pain with piccs in your arm is that you have to bag it and wrap it as best as you can to prevent direct water contact when you take showers. I would use the cling Saran Wrap, some use plastic trash bags with tape. Piccs are something you visibly see and can get tangled in clothes when your changing so make sure it's got a protective sleeve over it so it doesn't get caught up.

Hope this helps, if you have any other questions, please ask away.
