Abstract
PURPOSE: To investigate the various modes of vascular remodeling of atherosclerotic femoral arteries and determine the associations between type of arterial remodeling and clinical data (age, sex, and medical history) and inflammatory parameters. MATERIALS AND METHODS: Intravascular ultrasonography (US) of the femoral arteries was performed in 50 patients with clinical symptoms of peripheral vascular disease. To determine the arterial remodeling mode (expansive remodeling [ER], involving compensatory enlargement of the artery, or constrictive remodeling [CR], involving vessel constriction during progression of atherosclerosis), the cross-sectional areas (CSAs) of the external elastic membrane (EEM), lumen, and plaque-plus-media were measured every 0.1 mm by using three-dimensional reconstruction. Clinical, laboratory, and intravascular US data were compared in the different remodeling groups (dominant ER, dominant CR, or mixed remodeling) by using analysis of variance supplemented by Tukey-Kramer tests.
