Through July 2010. Data of analysis on file. Data based on an analysis of current literature: Several Medline searches were performed to identify publications pertaining to ePTFE synthetic vascular graft and vein infragenicular...
Open the catalog to page 3The Power is In the Surgeon’s Hands: Hemodynamics Can be Improved with Anastomotic Technique The current results of 3-D flow velocity studies suggest: 1,2 • The pre-cuffed graft does not offer the solution to the problem of poor hemodynamics in an end-to-side anastomosis. • A standard end-to-side anastomosis using a conventional ePTFE graft does not necessarily have poor flow. Flow can be improved by considering these important geometric factors: - Non-Planar Approach Angle • Bevel angle 12,13 • Anastomotic length 13,14 • Cross-sectional area 13,14 Current results confirm that a 30° bevel...
