[Retrospective study of the one-year patency of a cuffed polytetrafluoroethylene Venaflo-type graft placed for venous hemodialysis access].
OBJECTIVE
The objective of this study was to determine retrospectively the one year patency of a new polytetrafluoroethylene (ePTFE) graft with a cuff at the graft-vein anastomosis (Venaflo, Bard industries) placed for hemodialysis access.


METHODS
From April first 1999 to December thirty first 2001, 37 consecutive patients (56.8 medium age) underwent 39 Venaflo graft for hemodialysis in Vascular Surgery Section from Bordeaux University Hospital. All medical files have been reviewed at the end of the first year following the operation, by consultation or phone call from the referent nephrologist. Six patients deceased with a functional graft before the end of the study. The patency outcomes were calculated with Kaplan Meier life table method.


RESULTS
The one year primary patency is 60.03% with a 95% confident interval [43%; 77%] and secondary patency is 83.73% [70%; 96%].


CONCLUSIONS
The patency of cuffed ePTFE grafts for hemodialysis was satisfactory in comparison with the result of classic ePTFE grafts in the medical literacy. A large prospective multicentric medium term study would be necessary in order to confirm or not these results.
