What's the difference between a picc line and a hickman catheter?

Tunnel line. Both are use for long term intravenous access. Picc line use is shorter as compare to hickman. Hickman catheter is use tunnel line use for giving chemotherapy while picc line is use for long term antibiotics. Hickman is can not be place at bedside as compare to picc line. Picc line is inserted in arm mostly but something in neck by radiologist.
Picc . Is temporary. Hickman has a cuff which heals into skin. Hickman can last longer. Both catheters end up in same vein.
