Carotid artery stenting can cause geometric changes that may promote complications, particularly in patients with distal, highly calcified, circumferential plaques.
Carotid artery stenting can produce geometric changes to the artery that promote favorable conditions for complications and recurrent disease. Patients with circumferential, highly calcified plaques that are located relatively distal in the internal carotid artery are most likely to have post-stenting geometric changes.
Kamenskiy et al. (Mon,) studied this question.
