Interventional radiology placement of twin Tesio catheters for dialysis access: review of 75 patients.

PURPOSE: To evaluate the safety and efficacy of modern interventional radiology techniques and imaging guidance for placement of jugular vein twin Tesio hemodialysis catheters.

MATERIALS AND METHODS: Eighty-two sets (75 patients) of twin Tesio catheters were percutaneously placed in the right (n = 70) and left (n = 12) internal jugular veins with use of ultrasound (US) and fluoroscopic guidance. Immediate procedural and late complications were recorded. The efficacy of the Tesio system was also evaluated.

RESULTS: With US and fluoroscopic guidance, the technical success for access and catheter placement was 100%. Measured dialysis blood flow rate of greater than 375 mL/min was obtained in 95% of the patients and recirculation averaged 4.6% +/- 5%. An inadvertent common carotid artery puncture occurred in one (0.6%) patient and prolonged exit site bleeding occurred in another five patients (3%). Each of these was successfully controlled with compression. More chronically, catheter thrombosis and exit site infection occurred each at the rate of 0.16 episodes per 100 catheter days. All thrombosis and exit site infections responded to local thrombolysis and antibiotic therapy, respectively. Bacteremia occurred in 20 patients and required catheter removal in five patients. There was no clinical evidence of upper extremity or superior central vein thrombosis.

CONCLUSION: Placement of internal jugular, twin Tesio catheters with use of imaging and interventional techniques provides a safe and efficacious means of either short or long-term hemodialysis.
