Typical CTA images of the lower limbs of the patients. The severity of angiostenosis of the target lower limbs could not be alleviated after treatments based on the CTA images of the patients. Typical images are shown below for Pt 01 at baseline (a) and at the 1.5-month follow-up (b). Angiostenosis was detected in anterior and posterior tibial arteries as well as arteriae fibularis for Pt 01, especially for anterior tibial artery and arteriae fibularis of his left lower limb (white arrows). No significant improvement was observed in the angiostenosis status of these arteries, in which calcification was detected (white arrows in figures of cross section), at 1.5 months after treatments
