Figure 1 Modified lateral decubitus positioning technique and angiographic outcomes. (A, B) Right lateral decubitus position at 45° with right arm extended anteriorly on arm board; cylindrical towel rolls supporting axilla and trunk. (C) Pre-intervention DSA showing severe stenosis (80%) at right internal carotid artery origin. (D) Post-stenting DSA showing patent vessel with 30% residual stenosis. C-arm angulation: LAO 15°/Cranial 3°, optimized for lateral positioning.
