The objective of this study was to review our experience with using brachioaxillary Diastat vascular grafts (Diastat) compared to standard wall brachioaxillary PTFE grafts (sPTFE) in two similar groups of hemodialysis patients. We conducted a retrospective study comparing complications and graft survival in two similar groups (in terms of age, diabetes mellitus, surgical technique, and previous vascular access) of hemodialysis patients during the period 1994-1997 who had received Diastat (n = 40) or (sPTFE) (n = 40) grafts. We found that the Diastat graft for upper arm hemodialysis access has lower patency and higher complication rates than sPTFE grafts.
