- Fig 1.
A 35-year-old man with a spontaneous left cervical ICA dissection. A and B, Diffusion- (A) and perfusion-weighted (B) images reveal a large area of diffusion-perfusion mismatch, suggestive of poor collateral circulation. C and D, Left common carotid angiograms reveal severe focal stenosis of the proximal left ICA due to dissection and also show poor visualization of intracranial arteries. E, Angiogram immediately after self-expanding stent placement reveals complete restoration of normal luminal size of the left ICA and well-visualized intracranial arteries.
- Fig 2.
A 55-year-old man with a traumatic left intracranial ICA dissection. A, Left internal carotid angiogram reveals tapered occlusion of the left ICA just distal to the origin of the ophthalmic artery. Facial CT scan showed a linear fracture of the left optic strut adjacent to the left carotid artery (not shown). B, Lateral angiogram immediately after self-expanding stent placement shows recanalization of the ICA. Note incomplete expansion of the stent due to the remaining intramural hematoma (arrow). C, Follow-up lateral angiogram at 2 weeks reveals restoration of normal luminal size of the left ICA. Note complete resolution of the intramural hematoma and full expansion of the stent (arrow).
