Changes on related parameters of vascular lumen at different times during PTA: (a) changes of vascular lumen diameter; (b) changes of vascular lumen cross-sectional area; (c) cross-sectional circumferential distance of vascular lumen; (d) cross-sectional diameter of vascular lumen (A shows the diameter at proximal 5 mm, B shows the diameter of balloon angioplasty, and C shows the diameter at distal 5 mm); and the gray areas (a–c) represent the time of balloon angioplasty.
