BACKGROUND: Despite advances in secondary stroke prevention during the last several years, cryptogenic stroke remains associated with a high risk of recurrence. Studies have shown that the recurrence risk is higher in patients with large artery disease in which complex carotid plaques and carotid WEBs are identified. METHODS: This is a case series of six patients with cryptogenic recurrent stroke in which conventional imaging and extensive workup did not identify an etiology. Intravascular optic coherence tomography (OCT) was performed using a ballon-guided flow-arrest technique to identify possible covert carotid lesions. RESULTS: We present six cases in which, with the help of OCT, we identified three carotid WEBs with associated thrombosis and two ulcerated carotid artery plaques. Four patients were subsequently treated with endovascular stent placement without complications. OCT permitted the distinction between complicated carotid artery plaque and carotid WEB. CONCLUSION: Intravascular OCT is a feasible and safe approach to identifying patients with covert carotid wall abnormalities, like carotid WEBs and ulcerated plaques, that are amenable to carotid stenting to reduce recurrent stroke risk.
