May indicate preserved metabolic function despite reduced flow in asymptomatic occlusion; leaves open prospective validation of compensatory mechanisms.
What are the compensatory mechanisms in patients with asymptomatic carotid artery occlusion compared to controls?
Patients with asymptomatic carotid occlusion compensate by haemodynamic rather than metabolic mechanisms, preserving vasodilative capacities.
Kuwert et al. (1990) studied this question.
