CAROTID STENOSIS IMAGING WORKUP
Current techniques of high resolution contrast MRA and CTA are definitive.
A & B)CTA internal carotid artery stenosis, C)MRA carotids, D)CTA post stenting left internal carotid.

CAROTID, VERTEBRAL AND INTRACRANIAL STENTING
80 year-old male with severe CAD and previous left endarterectomy. Carotid stenting with distal brain protection. Balloon occludes distally while angioplasty and stenting is done, and this region is vacuum aspirated prior to letting the balloon down.
65 year-old male with contralateral occlusion and previous LICA
endarterectomy with restenosis.
EMERGENT PSEUDOANEURYSM STENTING
40 year-old female, sudden onset of LUE weakness, aphasia, resolved after 10 minutes. Angio shows dissection with pseudo aneurysm component. Placed single stent, protecting pseudo aneurysm. Follow up MRA 1 year later shows wide patency.
PSEUDOANEURYSM STENTING
48 year-old female in MVA with cervical spine fracture and vertebral artery pseudoaneurysm. Vertebral artery stenting jails off aneurysm with return to normal lumen. A)Pseudo aneurysm pre, B)pseudo aneurysm post stenting with cessation of filling within the aneurysm, C)CTA showing stent, D)CTA showing stent and flow.

BASILAR STENTING
67 year-old male with dizziness, visual changes. Failure of coumadin therapy (small occipital CVA). Place 3mm by 8mm stent in the inferior basilar artery.

INTRACRANIAL CAROTID STENTING
60 year-old male with R sided Am. Fugax and fatigue. Saw mostly blackness from R. eye and complained of B leg weakness. Pre intervention MRA showing severe narrowing at the petrous/ cavernous portion of the RICA. Angio A&B)pre, and C)post stenting. 3 months post stenting pt had significant improvement in vision r eye as well as markedly improved energy level and greater leg strength.
