Successful use of cuffed central venous hemodialysis catheters inserted percutaneously.
Although endogenous fistulae and grafts are preferred for permanent hemodialysis access, central venous catheters are often required for varying intervals when creating permanent access is not feasible. The prospective experience with 118 catheters in over a 3.5-yr period is reported; 93 (79%) were placed by percutaneous techniques, and 25 (21%) were placed by operative techniques. Seventy seven catheters (65%) were placed in the subclavian vein, 36 (31%) were placed in the internal jugular vein (usually right side), and 5 (4%) were placed in the femoral vein. Early postplacement complications were infrequent. Catheter function at last local follow-up ranged from several days to nearly 2 yr, averaging approximately 3 mo, even though many patients returned to their referring centers with a functioning catheter after only a short follow-up. Actuarial survival for percutaneously placed catheters was approximately 60% at 6 mo and 30% at 12 mo. Catheter failure occurred in 36% of cases, equally divided between malfunction (thrombosis refractory to fibrinolysis, extrusion, kinking, or related event) and infection with septicemia requiring removal. Such failure was not more frequent after percutaneous placement than after operative placement. Failure due to mechanical malfunction, but not that due to infection, tended to be less frequent among catheters placed in the internal jugular vein than among catheters placed in the subclavian vein. Finally, infection with septicemia involved 22% of all catheters and occurred at an average cumulated rate of approximately one infection per patient-year. Coagulase-positive staphylococcus was the most common organism isolated.(ABSTRACT TRUNCATED AT 250 WORDS)
