Placement issues of hemodialysis catheters with pre-existing central lines and catheters.

Abstract

It has been a widely accepted practice that a previous placed pacemaker, automatic implantable cardioverter defibrillators, or central line can be a contraindication to placing a hemodialysis catheter in the ipsilateral jugular vein. Fear of dislodging pacing wires, tunneling close to the battery site or causing venous obstruction has been a concern for surgeons and interventionalists alike. We suggest that this phobia may be unfounded. A retrospective review was conducted of patients in whom hemodialysis catheters were placed over a period of 10 years. For each hemodialysis catheter that was placed, perioperative chest X-ray performed was used to evaluate for pre-existing pacemakers and central lines. The position and laterality of placement of the hemodialysis catheter along with presence of arteriovenous fistula with functional capacity for access were noted. A total of 600 hemodialysis catheters were placed in patients over the period of 10 years. The mean age of the patients was 73.6 ± 12 years with a median age of 76 years. We found 20 pacemakers or automatic implantable cardioverter defibrillators and 19 central lines on the same side of the neck as the hemodialysis catheter that was placed in the ipsilateral jugular vein. No patient exhibited malfunction or dislodgment of the central line, the pacemaker, or automatic implantable cardioverter defibrillator or evidence of upper extremity venous obstruction based upon signs symptoms or duplex exams. Based on our experience, we suggest that placement of hemodialysis catheter in the internal jugular vein ipsilateral to the pre-existing catheter/leads is safe and spares the contralateral limb for arteriovenous fistula creation.
