FIG 3. Patient 11.
A, Anteroposterior angiogram of the left vertebral artery demonstrates irregularity of the lumen (arrow) and a 4–5-mm pseudoaneurysm (arrowhead) near the PICA origin.
B, Lateral angiogram of the left vertebral artery shows the small pseudoaneurysm (arrow).
C, Lateral angiogram of the right vertebral artery at the time of rehemorrhage 2 weeks after proximal occlusion of the left vertebral artery shows that the pseudoaneurysm (arrow) has not enlarged and the left PICA remains patent.
D, Anteroposterior angiogram of the right vertebral artery after delivery of coils across the vertebrobasilar junction into the pseudoaneurysm shows the lesion is occluded (arrow), with the PICA filling antegrade
