Even if placed and managed with the utmost care, it is rare that the short peripheral cannulas positioned in superficial veins of the arm can last for more than a week. It is more likely that they will face different complications (dislocation, phlebitis, thrombosis, occlusion, and extravasation) that will eventually always be configured as 'catheter failure' and the need to remove the device.
On the contrary, the ultrasound guided placement of long peripheral cannulas in the deep veins of the upper limb will allow a peripheral access for periods longer than a week (up to a month).
