Fig 2. A 60-year-old man presented with left-sided motor weakness. The patient had improvement of NIHSS score from 9 to 7. His mRS was 4 after 1 year.
A, The right ICA arteriogram shows complete occlusion of the right ICA. Good collateral circulation through the ophthalmic artery reveals no intracranial occlusion.
B, The left ICA arteriogram shows filling of the right anterior cerebral artery through the anterior communicating artery.
C, Vertebral angiogram shows a good leptomeningeal collateral circulation.
D, Microcatheter introduction reveals an occluded end of ICA below the level of the ophthalmic artery. The ICA occlusion could not be revascularized. There was a trigeminal artery variation.
