Damaged right internal jugular venous catheter status after Cox Maze IV procedure.
The Cox-Maze IV (CM-IV) procedure was introduced as a modification of the Cox-Maze III by using a bipolar radiofrequency clamp to replicate the majority of the long linear cut and sew lesions. The CM-IV maintained excellent success rates with low complication, and there are no reports of device-related complication in the literature. In this article, we present a patient who underwent aortic valve replacement with a concomitant CM-IV procedure. There was difficulty removing the right internal jugular catheter during the postoperative course, with evidence of catheter fracture on chest radiograph. Upon catheter removal by Interventional Radiology, the distal segment had sustained a radiofrequency burn strike that had melted the involved segment with significant loss of catheter integrity. Of the several events that have occurred in our high volume Maze program, this resulted in changing the anesthesia protocol by using shorter catheters that will be less likely to become caught in the jaws of the bipolar clamp during the performance of the intercaval line of the CM-IV.
