Background

The aim of this study was to describe early and late results of proximal and distal ligation for popliteal aneurysm (PA), combined with bypass, with particular reference to the fate of the excluded aneurysm.

Method

Of a cohort of 116 patients with PAs, 66 were treated with bypass and ligation. Graft patency was determined by duplex surveillance. In addition, 17 patients with bypassed PAs underwent a total of 33 duplex scans to determine flow within the aneurysm and change in size.

Results

For initially patent PAs, 3‐, 5‐ and 8‐year primary bypass graft patency was 78, 78 and 51 per cent respectively. These rates were not statistically significantly different from those following bypass for thrombosed PA, 3‐ and 5‐year primary patency being 72 and 65 per cent respectively. No PA produced further symptoms after bypass and ligation. No flow was seen in any aneurysm at follow‐up. Only one showed an increase in size.

Conclusion

Proximal and distal ligation with bypass produced satisfactory long‐term patency with good exclusion of the PA. Copyright © 2006 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
