The reported picco catheter was returned for investigation.The reported problem was confirmed by microscopic inspection.A cut was found at 4.7 cm below the tip of the catheter together with a deformation of the material.The tip had been separated at exactly this point (to 2/3 by the cut and to 1/3 by the forces applied during removal of the guidewire with the dilator).According to our information a scalpel was used during removal of the dilator, so the cut can be explained by off-label-use of a scalpel (used with dilator in place) during application of the catheter.Please note, this event is being filed as a retrospective mdr as a result of a review of our complaint database.

It was reported that during application of a picco catheter on a patient, the dilator could not be pulled out over the guide wire in place due to a high resistance and had to be removed together with the guide wire.After this it was noticed that the tip of the dilator had separated and had remained in the blood vessel from where it was transported with the blood stream further along the circulation.It finally got stuck in the knee artery (art poplitea), from where it had to be removed surgically.The final patient outcome was no injury.(b)(4).
