Left vertebral artery anteroposterior angiograms. A, Small, shallow, broad-neck aneurysm at a nonbranching point on the distal basilar artery (arrow), which was not present on the initial CTA, considered a blister aneurysm. B, Control angiogram after a single PED deployment into the left posterior cerebral artery shows persistent filling of the aneurysm, but there was increased stasis on the rotational angiogram (not shown). Note the contrast washout in the basilar artery. C, Two-month follow-up angiogram shows complete occlusion of the aneurysm and reconstruction of the parent vessel, with patency of the covered arteries.

A, 3D volume-rendered reformat of a right vertebral artery rotational angiogram. The broad-neck aneurysm arising at a nonbranching site of the right intracranial vertebral artery, distal to the PICA origin, was considered a dissecting/dysplastic aneurysm. B, Single-shot image and venous phase right vertebral artery angiogram in working projections after a single PED. There is a 0.014-inch microcatheter in the aneurysm lumen. Note the contrast stasis in the aneurysm sac. C, Control angiogram after loose-packed coiling of the aneurysm sac to increase the thrombosis rate, with good immediate angiographic results. D, Right vertebral artery anteroposterior angiogram showing left subclavian steal, which contraindicated parent vessel occlusion.

A, 3D volume-rendered reformat of a left ICA rotational angiogram shows a giant distal supraclinoid ICA aneurysm. B, Lateral ICA angiogram after a single PED deployment shows a significant flow effect with contrast stasis and layering within the aneurysm sac. C, Lateral ICA angiogram after loose packing of the aneurysm sac, with higher packing attenuation at the dome near the presumed ruptured site. There is persistent filling of the aneurysm sac and a satisfactory flow effect. D, Non-enhanced CT hours after the procedure. The patient had an acute decline in his neurologic status. There is a large parenchymal hematoma with contrast material cranial to the coil mass and in the ventricles and subarachnoid space. The patient died 5 days later secondary to persistent raised intracranial pressure.
