Key result
Carotid recanalization with angioplasty and stenting resulted in the adaptively narrowed distal carotid regaining its morphology 1 week after the procedure, rather than immediately.
Why the study?
Does angioplasty and stenting restitute adaptively narrowed distal carotid morphology in a patient with carotid occlusion?

Does angioplasty and stenting restitute adaptively narrowed distal carotid morphology in a patient with carotid occlusion?
Carotid adaptive narrowing distal to an occlusion may not regain its original morphology immediately after recanalization, but can restitute several days later.
May warrant delayed imaging to confirm carotid remodeling after recanalization; leaves open optimal follow-up timing in similar occlusions.
Severe carotid stenosis or occlusion may cause insufficient blood flow and lead to distal artery wall collapse and extensive lumen contraction. Whether this 'adaptive narrowing' can restitute after carotid recanalization is unclear. We report a patient with global ischemia due to occlusions of bilateral carotid and right vertebral arteries. The occluded left carotid was recanalized successfully with angioplasty and stenting. The adaptively narrowed distal carotid did not restitute immediately but regained its morphology 1 week after the procedure. Carotid adaptive narrow distal occlusion or stenosis may not regain its original morphology immediately but several days after recanalization. This knowledge is instructive for treating occlusive carotid diseases.

Xu et al. (2015) conducted a case report in Global ischemia due to occlusions of bilateral carotid and right vertebral arteries (n=1). Angioplasty and stenting was evaluated on Restitution of adaptively narrowed distal carotid morphology. Carotid recanalization with angioplasty and stenting resulted in the adaptively narrowed distal carotid regaining its morphology 1 week after the procedure, rather than immediately.
