Internal Carotid Artery Occlusion - Case 3
- A 57 year-old man presented with a mild headaches. His examination was normal. An MRI of the brain suggested an abnormality of the left internal carotid artery which led to the patient undergoing a cerebral angiogram.
- Cerebral Angiogram. (Left) right internal carotid injection - AP view; (Right) left common carotid
artery injection, AP view. Note that the left internal carotid artery is
completely occluded. The entire right hemisphere is being perfused from the contralateral side. Thus, with an intact circle of Willis, some patients can be completely asymptomatic from a carotid occlusion.
