Langzeitergebnisse klinischer Stadienverbesserung nach femoropoplitealem ePTFE-Bypass

Summary

Although the patency rate is the normally accepted measure of success of an arterial reconstruction the improvement of the clinical state is the decisive point of a surgical treatment. We therefore studied the clinical improvement rates following femoropopliteal ePTFE bypass reconstruction by comparing them to the patency rates. The 5-year patency rate of the bypasses to the upper popliteal segment was 53.1 ± 7.6 %, the clinical state was improved in 49.1 ± 8.1 % of the patients. 47.6 ± 6.3 % of the bypasses to the lower popliteal segment were open after 5 years, but we saw a better clinical state of 39.7 ± 6.2 % of the patients after this time. These differences were not statistically significant. Differentiating the clinical success of a reconstruction due to the run off, the clinical state of the patients and the receiving segment of the bypass, differences between the patency rates and the clinical improvement rates were evident, especially in reconstructions to the lower popliteal segment in a patient clinical stadium III/IV after Fontaine with a poor run-off situation.
