Gore-tex graft vs ptfe graft

Frequently Asked Questions
Can you cross-clamp the graft?
As with all ePTFE grafts, care should be taken to avoid mechanical damage to or disruption of the graft. Use the appropriate atraumatic or guarded (for example, rubber shod) clamps. Avoid repeated, localized clamping or excessive clamping on any section of the graft.
Can you incorporate the densified ePTFE support sections (the 'rings') in an anastomosis of the GORE® INTERING® Vascular Graft?
Yes, the densified ePTFE supports are designed such that suture can be passed through them. These densified ePTFE sections at the anastomosis can assist in maximizing the anastomotic opening.
Does the GORE® INTERING® Vascular Graft radial support compromise ingrowth and tissue attachment?
We have data showing that tissue ingrowth still occurs through the radial support. In contrast, no ingrowth occurs through the full density PTFE or FEP material used for rings or spiral support on other grafts.
Have you ever had a confirmed allergic reaction to ePTFE?
We have never had a confirmed allergic response to ePTFE. PTFE is the most inert substance known and is very biocompatible.
Is there a profile on the lumen du • Manufacturers of polytetraflouroethylene (PTFE) grafts used for chronic hemodialysis access describe specific advantages for their respective grafts, which presumably result in greater graft patency rates, reduced complications and decreased overall costs. There are few data available in the literature to support or contradict these alleged benefits. Therefore, this prospective study was undertaken to evaluate and compare patency rates, complications and costs between two of the leading brands of PTFE that are currently being marketed for use as hemodialysis access grafts. Totals of primary PTFE grafts ( Gore-tex (W. L. Gore and Associates, Flagstaff, AZ) and 90 Impra (C. R. Bard Inc., Tempe, AZ)) were implanted in consecutive patients with end-stage renal disease. A policy of non-interventions was employed for patent grafts, as no attempt was made to assist primary patency. Grafts that occluded during follow-up underwent secondary revision to maintain patency. There was no difference in primary and secondary patency by life-table analysis between Gore-tex and Impra grafts at 2 years ( • Background: Placement nearby maintenance line of attack a well-functioning vascular opening are imperative for distribution of enough hemodialysis.
