Intracranial arterial dolichoectasia and small-vessel disease in stroke patients.
Two studies found that stroke patients with intracranial arterial dolichoectasia (IADE) had lacunar infarction more often than the control subjects. The relation between IADE and other manifestations of small-vessel disease (multilacunar state, leukoaraiosis, and état criblé) was not investigated. The magnetic resonance images of 510 patients with brain infarction in the Etude du Profil Genetique de l'Infarctus Cerebral (GENIC) study were evaluated for the diagnosis of multilacunar infarction (>1 lacunar infarct), leukoaraiosis (assessed in periventricular and subcortical regions according to Scheltens and colleagues' scale, with severe leukoaraiosis defined as a score > 8), état criblé (using a semiquantitative score ranging from 0-8, with severe EC > 4), and IADE (using the consensus method). ⋯ The factors significantly associated with état criblé were older age and a familial history of stroke. IADE in stroke patients was independently associated with parenchymal manifestations of small-vessel disease. These conditions may have in common underlying pathophysiological processes.
