H6 code 100: both ends of catheter had been cut by user.
Catheter most likely not advanced over locking bead on port connector tube.
History: the subject port was for evaluation and analysis.
The catheter had separated from the port housing.
Analysis: the port was returned in three separate components: the catheter, the catheter lock assembly, and the port housing.
The catheter measured 9.
8 inches long, one end of which exhibited an approximately square instrument cut, and the other end of which exhibited an angled instrument cut.
The location of the insertion depth markings indicated that although the port-catheter assembly was supplied as a pre-attached model, the physician had implanted it as a detached model.
Examination of the catheter revealed a circumferential wear mark on the inner diameter near the angled end.
There was no other evidence of a connection to the port housing.
Conclusion: the most likely cause of the catheter separation from the port housing is that during connection to the housing, the catheter was not advanced over the locking bead of the connector tube, resulting in subsequent detachment of the catheter.
