Representative case of easy navigation. (A) CTA image of the right SA and CCA with an illustration of measurements. SA height is 32.4 mm and CCA length is 31.5°. (B) Lateral angiographic view revealing stenosis of the right carotid artery. (C) Anterior–posterior X-ray view during balloon dilatation after stent placement. The 7-F Optimo BGC (black arrow) is navigated from the right RA to the CCA. (D) Post-procedural lateral angiographic view showing good revascularization.

CTA: computed tomography angiography; SA: subclavian artery; CCA: common carotid artery; BGC: balloon guide catheter.
