Figure 2. Biomechanical changes in vein grafts following transposition to arterial circulation. (A) Normalization of radius to wall thickness ratio over time in rabbit jugular vein to carotid interposition grafts. (B) Similarities in sonographic spectral flow patterns in unstented (left) and stented (right) porcine saphenous vein grafts. (C) Pressure to cross-sectional area ratio relationships in externally supported and non-supported saphenous veins from domestic hogs. Part A was adapted from Ref.^[16]; part B was adapted from Ref.^[15]; part C was adapted from Ref.^[21].
