The lumen at the initial segment of the left subclavian artery is slightly narrowed, the vascular walls at the proximal and middle segments are diffusely thickened with local lumen occlusion and moderate stenosis, and the distal lumen is slender. The wall of the thoracic-abdominal aorta is slightly thickened with multiple calcifications, whereas the lumen is slightly narrowed. Obvious luminal stenosis can be observed at the beginning of the abdominal trunk, as well as at the beginning portion of the bilateral renal arteries
