Étude rétrospective monocentrique de la survie et des complications thrombotiques et infectieuses de deux cathéters veineux centraux d’hémodialyse

Abstract

PurposeIn a monocentric retrospective study, two tunneled hemodialysis catheters have been compared: a twin cylinder catheter (Dualcath) and a split tip catheter (Hemosplit). Patients and methodsPatients who got catheters from January 1st 2007 to December 31st 2008 have been selected. Thrombotic events, as well as infectious events, were recorded in their dialysis file during this period of time. Main resultsThe study was carried out on 50 patients. Thirty of them were given Dualcath, 23 were given Hemosplit, and three both of them. A Kaplan-Meier analysis has enabled to draw up the catheter survival curves, and the log-rank test enables to establish a survival of 93.1% at 20 months for Dualcath while 42.2% for Hemosplit. As far as the thrombotic complications with catheter incident are concerned, their incidence is 25.5 and 46.4 out of 1000 catheter-days (P<0,0001). The ones with catheter manipulation have incidences of 6.78 and 9.33 out of 1000 catheter-days, respectively for Dualcath and Hemosplit (NS). Dualcath presents catheter-related infections with a rate of 4.38 out of 1000-catheter days while 5.07 for Hemosplit (NS). ConclusionThe Dualcath catheter presents a better survival than the Hemosplit catheter as well as weaker incident type thrombotic complications.
