The intracranial segment of the optic nerve, crossed near the chiasma by the anterior cerebral artery and fixed anteriorly at its entry into the optic foramen, is particularly vulnerable to compression by vascular deformities of the internal carotid artery or its branches. Aneurysms arising in this region may be surgically inaccessible directly, because of their size or because they arise from ...

BACKGROUND Takayasu arteritis is a rare, chronic large vessel vasculitis involving the aorta and its primary branches. As the disease progresses, the active inflammation of large vessels leads to dilation, narrowing and occlusion of the arteries. Arterial dissection is due to separation of the layers of the arterial wall resulting in a false lumen, where blood seeps into the vessel wall. Neurol...

Oculomotor nerve palsy frequently occurs because of external compression by an internal carotid-posterior communicating artery aneurysm and diabetes mellitus. In addition, pontine infarction, cavernous sinus tumors, demyelinating disease, and autoimmune disorder are well-known causes of oculomotor nerve palsy. However, cases of complete oculomotor nerve palsy by neurovascular conflicts presente...

RATIONALE Blunt cerebrovascular injury (BCVI) is a rare complication that may occur after craniocervical trauma. The current literature is limited to extracranial carotid artery injuries; however, no reports have been published on blunt intracranial carotid injury (BICI), especially those associated with optic nerve injury. PATIENT CONCERNS Here we report on 3 BICI cases that demonstrated opt...

PURPOSE We report our initial experience using a detachable microvascular plug system to occlude the internal carotid artery during endovascular treatment of high-flow carotid cavernous fistula. CASE AND TECHNIQUE An 87-year-old patient was admitted for acute-onset double vision with associated right-eye ptosis. Exam revealed a pupil-sparing, partial right third cranial nerve palsy. MRI showe...

A 21-year-old woman presented with an unruptured large intracavernous aneurysm, which was spontaneously revascularized via unusual collateral pathways a short time after extracranial-intracranial bypass and surgical ligation of the proximal internal carotid artery. The patient had been treated for a large basilar trunk aneurysm with intraaneurysmal embolization using Guglielmi detachable coils,...

our aim was to report techniques and our experience in one-stage angioplasty and stenting of ostium of left common carotid and left internal carotid arteries in an octogenarian man with transient ischemic attack, who was completely recovered from neurologic insults short time after the procedure. an 81-year-old man presented with a transient ischemic attack. neurologic examination showed left s...

Figure 1: A. (Top Left) Coronal T2 MRI: Arrowhead showing right cavernous carotid displacing optic chiasm superiorly. Arrow highlighting left ACA displacing the left portion of the optic chiasm inferiorly. Also note focal hyperintensity in the right chiasm. B. (Top Right) Coronal T2 MRI: Arrowhead showing displacement of optic chiasm superiorly by supraclinoid cavernous carotid. C. (Bottom Left...
