The Demers atrial catheter: experience with a single-lumen silicone catheter as short- and long-term access for hemodialysis.
The Demers catheter is a silicone atrial catheter with a dacron cuff used as short- and long-term access for hemodialysis. It was implanted in 316 patients between January 1, 1987 through May 31, 1991. Data on these implantations were retrospectively analyzed and are reported here. Follow-up and analysis was possible in 404 of 417 Demers catheter implantations. The mean age of patients in this study was 61 years. For short-term use (< 91 days) 153 catheters were implanted in 135 patients, for long-term use (> 90 days) 251 catheters in 181 patients. The median life span of all 404 catheters was 87 days. The median life span for long-term use was 150 days (2-1302) per catheter and 220 days (92-1717) per patient. Catheter malfunction (arterial blood flow < 200 ml) was encountered every 876 days in the running time of the catheter. Twenty percent (n = 80) of the catheters were explanted because of complications. These included 42 cases of catheter malfunction and 22 cases of infection.
