Analysis of reverse flow in the descending aorta (DAo) based on five emitter planes in the DAo. The first plane was positioned immediately distal to the left subclavian artery (LSA) and all subsequent planes 2–5 were placed downstream in 10mm intervals. Diastolic DAo flow reversal reaching the LSA, CCA, and BT was found in a total of 20, 8, and 3 stroke patients, respectively. The table provides a summary of the DAo origin for retrograde flow reaching the different supra-aortic branches. The gray shaded surface shows the aortic anatomy based on the 3D PC-MRA data. AAo = ascending aorta, BT = brachiocephalic trunk, CCA = common carotid artery.
