The objective of this work was to develop a system for three-dimensional (3D) reconstruction of the femoropopliteal artery from two angiographic views and to quantify the in vivo 3D deformations in 18 patients before balloon angioplasty and after primary stent implantation. The procedure had an insignificant effect on the bending behavior of the artery, as the average mean curvature change within the lesion remained constant before (0.04 cm ± 0.03) and after stent implantation (0.03 cm ± 0.04). A significant effect of stent implantation was measured in terms of a decrease in arterial shortening during leg flexion.
这项工作的目的是开发一种系统，用于从两个血管造影视图对股腘动脉进行三维（3D）重建，并量化18例患者在球囊血管成形术前和初次支架植入后的体内3D变形情况。该手术对动脉的弯曲行为影响不显著，因为病变部位内的平均曲率变化在支架植入前（0.04 cm±0.03）和植入后（0.03 cm±0.04）保持恒定。就腿部弯曲期间动脉缩短的减少而言，测量到了支架植入的显著效果。
