Detailed illustrative imaging of Case 5 demonstrating tandem occlusions and successful recanalization using the coaxial balloon technique. (A)–(C) Baseline CT, CTA, and CTP performed 190 min after the symptom onset. (D)–(P) Left carotid angiography showing ICA-origin occlusion and tandem intracranial occlusion and successful recanalization of the vessels after the procedure. (Q) CTA follow-up 1 week after the procedure showing patency of the carotid stent and M1. CT, computed tomography; CTA, computed tomography angiography; CTP, computed tomography perfusion; ICA, internal carotid artery.
