OBJECTIVE: To measure non-invasively the impedance index of a range of geometries of PTFE end-to-side anastomoses (ESA). DESIGN: In vitro experiments using a custom-built flow rig. SUBJECTS: Anastomoses constructed at each angle. (15 degrees, 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees) for both standard and cuffed ESA. RESULTS: The impedance index of each ESA increased non-linearly with flow rate. The impedance index at a given flow rate was reduced by decreasing the anastomotic angle and further reduced by the addition of a Miller cuff. CONCLUSIONS: The reduction in impedance index achieved with a Miller cuff may help to explain the improved patency rates of femoropopliteal grafts incorporating a cuff. |
