From: Influence of Vertebrobasilar Stenotic Lesion Rigidity on the Outcome of Angioplasty and Stenting
Hard lesion in a patient with atherosclerosis. A 73-year-old man suffered from recurrent stroke in the bilateral occipital regions. Left vertebral angiogram showed atherosclerosis with 90% stenosis of the mid-basilar artery (a, arrow). VW-MRI of the stenotic lesion of the mid-basilar artery revealed low signal on fat-suppressed T1WI (b, arrow) and T2WI (c, arrow) and strong enhancement on contrast-enhanced fat-suppressed T1WI (d, arrow). The PTAS failed because the stenotic lesion could not be fully dilated with the PP up to 7 atm (e, arrow). The Wingspan stent system could not pass through the stenotic lesion. His case was also complicated by a perforator infarct in the left pons (f, arrow).
