From: Influence of Vertebrobasilar Stenotic Lesion Rigidity on the Outcome of Angioplasty and Stenting
Soft lesion in a patient with dissection. A 44-year-old man suffered from recurrent headache and dysarthria for 1 week. Brain MRI showed multiple recent infarcts in the bilateral cerebellar hemispheres on DWI. Right vertebral angiogram showed acute dissection with 85% stenosis of the right distal vertebral artery (a). VW-MRI of the right distal vertebral artery showed a high-signal intramural hematoma on fat-suppressed T1WI (b, arrow) and T2WI (c, arrow) and focal strong enhancement of the intramural hematoma on contrast-enhanced fat-suppressed T1WI (d, arrow). During the PTAS, the PP was 3 atm. A 3.5 × 20 mm balloon-expandable stent was placed in the right distal vertebral artery. In a 4-year follow-up, CTA with curved multi-planar reconstruction showed good patency of the stent (e, arrow).
