case_images: Computed tomography angiography (CTA) demonstrating stenosis of the left subclavian artery. (A) Axial CTA image showing atherosclerotic calcification of the aortic arch (solid white arrow). (B) Axial view of the left subclavian artery reveals a thick calcified plaque (hollow white arrow), causing severe luminal stenosis. (C) Coronal CTA image showing proximal stenosis of the left subclavian artery (white arrowhead).

case_images: Further evaluation was advised, and a chest CTA performed on December 26, 2018, confirmed stenosis of the left subclavian artery due to atherosclerosis, thus diagnosing SSS (Figure 1).
case_images: Moving average trendline of systolic blood pressure (SBP) difference. During treatment for Chinese herbal medicines (CHMs) Group B, the difference in SBP between the two arms steadily reduces. CHMs Group A: Yi-Qi-Cong-Ming-Tang, Liu-Wei-Di-Huang-Wan, Yuan-Zhi (Radix Polygalae), and Shi-Chang-Pu (Rhizoma Acori Tatarinowii); CHMs Group B: Xue-Fu-Zhu-Yu-Tang, Zhi-Gan-Cao-Tang, Shan-Zha (Fructus Crataegi), and Jue-Ming-Zhi (Semen Cassiae).

case_images: Additionally, the moving average trendline in Figure 2 demonstrates that there was no change in bilateral BP during the CHMs Group A treatment, whereas a steady decline was observed during the CHMs Group B treatment.
