(A) Diffusion-weighted image showing recent infarction in the left occipital lobe. (B) CT perfusion showing prolonged mean transit time in the left lobe supplied by the stenotic basilar artery (BA). (C) Angiogram showing 90% stenosis in the middle segment of the BA. (D) After pre-dilation, an angiogram showing that the stenosis was partially resolved and that the tip of the microwire (arrow) was found outside the left posterior cerebral artery (PCA). (E) Angiogram showing that the P1 segment of the left PCA was curved and the right vertebral artery and BA were straight. (F) A pilot microwire was advanced over the lesion to the distal P1 segment of the left PCA, paralleling the entrapped Synchro microwire for implantation of an Apollo balloon-expandable stent. (G) After stenting, an angiogram showing the resolution of the stenosis. (H) The microwire tip was inadvertently dislocated from the left PCA during the manipulation to leave the microwire in place in the patient.
