A PICC line is a peripherally inserted central catheter that has a long tube that is inserted through a vein, typically in your arm, that passes through larger veins near your heart. The advantage to the PICC line is it removes the need to have an IV inserted directly into a vein in your hand/arm with each chemotherapy infusion. The PICC line requires weekly dressing changes and you have to keep it dry at all times to avoid infection.
