[Secondary migration of a central venous catheter linked to an implantable port]

The secondary migration of the distal part of a central venous catheter with implantable port is rarely described. This study reports a case in which the distal part of a catheter with implantable port moved spontaneously, a month after its implantation in a branch of the internal jugular vein without any other complication. The discussion is about modalities, frequency and explanation mechanisms of the complications due to central catheters. The conclusion insists on systematical radiologic control of the position of implantable port with central venous access, and in case of bad working or any sign of thrombo-phlebitis.
