Der sekundäre femorodistale PTFE-Bypass

Summary

Retrospective analysis of 517 infrainguinal bypasses with polytetra- fluoroethylene (PTFE) for treatment of limb-threatening ischemia was performed to evaluate the success of secondary revascularization after failure of a previous graft. There were 406 primary and 111 secondary femorodistal bypasses. Most of the secondary procedures were femorotibial bypasses (n = 81). There was a preponderance of diabetes (56%) in the patient population with primary bypass and of smoking history (74%) in the group with secondary bypass. Acute ischemia, previous iliac reconstruction, and poor angiographic runoff were seen more often in patients with secondary reconstruction. Three years after bypass procedure secondary cumulative patency rate is lower in patients with secondary PTFE-grafts (22% vs. 52%). In conclusion, cumulative patency rate is significant lower in secondary grafts. This difference is independent from distal runoff or certain risk factors.
