The decrease in luminal area cannot be attributed to plaque increase alone. Arterial wall shrinkage is a paradoxical mechanism that may contribute to severe luminal narrowing of the atherosclerotic human femoral artery.

Abstract-Atherosclerosis is common in the adductor hiatus region. The aim of this study was to evaluate atherosclerosis in relation to themorphological structure of the femoropopliteal region. Two anatomic features are thought to play an important role in the origin of these lesions: (1) curvature of the vessel, which may lead to unfavorable local hemodynamic factors that change during leg flexion; and (2)

In the majority of atherosclerotic femoral arteries, significant compensatory enlargement could not be determined. It is inferred that arterial remodeling in response to plaque formation may vary among individuals.
