3D-TOF MRA and left-VA DSA. (A) 3D-TOF MRA revealing left-ICA occlusion with good cross flow in the left-MCA and ACA and hypoplastic aspect of both VA and proximal BA (arrow) usually seen in persistent PTA. (B) Left VA DSA confirming small VA, proximal BA and localized intravascular filling defect on the mid basilar segment proximal to the SCA origin, corresponding to thrombus extension from the PTA (arrow). (C) Left common carotid artery DSA showing flamed-shaped occlusion of the left ICA, characteristic of occlusive dissection (arrow).
