In patients on chronic hemodialysis, peripheral vascular access exhaustion is the main indication for permanent venous cannulation. Since the data available on this topic is scarce, we reviewed the survival and major long-term complications of permanent central hemodialysis access (CVP) in 45 hemodialysis patients that underwent 65 catheter insertions (18 Permcath and 47 Tesio Catheter) from June 1989 to June 1997. All patients had been treated with ASA or warfarin. Catheter survival was analyzed by Kaplan-Meier analysis. One-year, tow-year, three-year and four-year survival was 74%, 56%, 56% and 51% respectively. The main problems were infection in 5, thrombosis in 5 and accidental exit of the catheter in 9 patients. Two patients died of endocarditis due to sepsis. The probability of absence of infection was 96%, 88%, and 88% at one, two, three and four years, respectively. The probability of absence of thrombosis was 89%, 84%, 84% and 80% at one, two, three and four years, respectively. Our data show that CVP might represent an effective long-term blood access for chronic hemodialysis.

Abstract
In patients on chronic hemodialysis, peripheral vascular access exhaustion is the main indication for permanent venous cannulation. Since the data available on this topic is scarce, we reviewed the survival and major long-term complications of permanent central hemodialysis access (CVP) in 45 hemodialysis patients that underwent 65 catheter insertions (18 Permcath and 47 Tesio Catheter) from June 1989 to June 1997. All patients had been treated with ASA or warfarin. Catheter survival was analyzed by Kaplan-Meier analysis. One-year, tow-year, three-year and four-year survival was 74%, 56%, 56% and 51% respectively. The main problems were infection in 5, thrombosis in 5 and accidental exit of the catheter in 9 patients. Two patients died of endocarditis due to sepsis. The probability of absence of infection was 96%, 88%, and 88% at one, two, three and four years, respectively. The probability of absence of thrombosis was 89%, 84%, 84% and 80% at one, two, three and four years, respectively. Our data show that CVP might represent an effective long-term blood access for chronic hemodialysis.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
