Baseline images of the patient including (A) CT scan, (B) diffusion-weighted image MRI, and (C) mean transit time map of MRI are showing.

A: Angiography shows occlusion at cavernous segment of the internal carotid artery on the right. B: A-P angiography shows that Solitaire AB stent is used as a temporary bypass for the remaining middle cerebral artery occlusion after recanalization of the ICA. C: Final lateral angiography shows inadvertent detachment of the stent and the remaining distal ICA occlusion. ICA: internal carotid artery.

Surgical finding of the acutely angled and circumferentially calcified distal ICA (A) before arteriotomy is showing. Surgically removed Solitaire AB stent is containing the main thrombi at the distal part of the stent strut (B). A-P and lateral angiography immediately after surgery is showing full recanalization of the occlusion (C and D). Bone window image of a baseline CT scan shows severely and circumferentially calcified supraclinoid segment of the ICA (arrow), which corresponds to the surgical finding (E). ICA: internal carotid artery.
