Arterial clamping leads to stenosis at clamp sites after femoropopliteal bypass surgery - 14/08/15
Abstract |
Background |
To date, the incidence and clinical relevance of arterial stenosis at clamp sites after femoropopliteal bypass surgery is unknown.
Methods |
Ninety-four patients underwent a femoropopliteal bypass in which the arterial inflow and outflow clamp sites were controlled by the Fogarty-Soft-Inlay clamp and marked with an hemoclip. The number of pre-existing atherosclerotic segments, clamp force, and clamp time were recorded and the occurrence of a stenosis at the clamp site was determined.
Results |
After a mean follow-up of 83 months, a significant stenosis was confirmed at 23 of the 178 clamp sites (12.9%; 95% confidence interval 8.4 to 18.8). The mean number of pre-existing atherosclerotic segments (P = .28) and the mean clamp force (P = .55) was similar between the groups with and without a stenosis. There was a significant difference regarding clamp time between the group with and without a stenosis (38 minutes and 26 minutes, P = .001).
Conclusion |
Arterial clamping, even with the Fogarty-Soft-Inlay clamp, can lead to clamp stenosis and seems to be related to the duration of clamping, but not to pre-existent atherosclerotic burden.

• | Arterial clamping during femoropopliteal bypass surgery can lead to a stenosis at the clamp site. |
• | There is a significant relationship with the duration of arterial clamping and the occurrence of a stenosis. |
• | Visual assessment of the pre-existing atherosclerotic burden is not a predictor for the occurrence of an arterial stenosis after clamping. |
• | Clamping force appears to play no part in the development of an arterial stenosis. |
