Effects of metabolic syndrome on multi-vessel lesions of symptomatic intracranial atherosclerosis

To explore the effects of metabolic syndrome (MS) on multi-vessel lesions of symptomatic intracranial atherosclerosis. During April 2009 and October 2010, a total of 139 consecutive hospitalized patients with symptomatic intracranial atherosclerosis were recruited to undergo magnetic resonance angiography (MRA) or/and CT angiography (CTA) or/and digital subtraction angiography (DSA) to measure the stenotic degree and numbers of intracranial atherosclerosis. They were divided into 2 groups according to lesion numbers: single and multi-vessel lesions. MS was defined by the criteria of the Adult Treatment Panel III to examine the incidences of MS. The risk factors were analyzed for multi-vessel lesions of symptomatic intracranial atherosclerosis to explore the relationship between MS and multi-vessel lesions. Among them, 210 intracranial atherosclerotic lesions were documented. Fifty-nine (42.4%) patients had two or more lesions (group with multi-vessel lesions). The incidence of MS was 70.5%. The rates of MS in
