(a) CT angiogram (CTA) of the head and neck showing the diseased cervical carotid artery segment with pseudoaneurysm formation, dissection flap, and intervening arterial stenosis. (b) Lateral and (c) AP view digital subtraction angiograms (DSA) before deployment of the pipeline embolization device (PED) show a high cervical carotid pseudoaneurysm and vessel stenosis. (d) Immediate DSA following PED placement shows improved vessel caliber. (e) CTA post-treatment demonstrating the span of the telescoping PED stents and immediate improvement in vessel caliber and aneurysm occlusion. (f) DSA at 6-month follow-up showing the pseudoaneurysm remaining occluded and normal contour of the cervical carotid artery
