Large cerebral artery involvement in CADASIL.

The authors evaluated the involvement of large cerebral artery in 13 patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) with angiography (12 MR and one conventional). Five patients (38%) showed stenosis: at the middle cerebral artery in three, vertebral artery in one, and the internal carotid artery in one. The stenosis persisted on follow-up angiogram in two patients. There were no differences in risk factors between patients with angiographic abnormality and those without, suggesting occasional involvement of large vessels in CADASIL.
