Key result
Crossed-leg position linked to ~50 mm femoropopliteal artery shortening and conformational changes versus straight-leg.
Why the study?
Does leg movement from a straight to a crossed position alter the conformation of the femoropopliteal artery in patients with peripheral arterial disease?
Observational (n=9)
Does leg movement from a straight to a crossed position alter the conformation of the femoropopliteal artery in patients with peripheral arterial disease?
Mean Difference: 50.3
p-value: p=<0.001
Significant conformational changes, including shortening and increased curvature, occur in the femoropopliteal artery during leg movement, highlighting biomechanical forces relevant to endovascular stent design and failure.

Positional leg changes may stress femoropopliteal stents in PAD; hypothesis-generating for device design and leaves clinical impact open.
Klein et al. (2009) conducted an observational in Peripheral arterial disease (n=9). Crossed-leg position vs. Straight-leg position was evaluated on Mean shortening of the femoropopliteal artery (MD 50.3 mm, p=<0.001). Movement from the straight-leg to the crossed-leg position induced significant conformational changes in the femoropopliteal artery, including a mean shortening of 50.3 mm (P<0.001).
