Study Of The Relationship Between The Plasma Bilirubin Leveland Intracranial Arterial Stenosis

Objective：To explore the relationship between the Plasma bilirubin leveland intracranial arterial stenosis.Methods：159adult patients with cerebral infarction experienced digitalsubstraction angiography(DSA) were enrolled，and105patients with potentialintracranial arterial stenosis (grade＞50％，at least one vessel) and54patientswithout stenosis or mild grade(grade≤50％)were included as control．Plasmabilirubin level was analyzed and conventional risk factors of cerebral infarctionsuch as gender，age，hypertension，diabetes，long-smoking，and plasma levelsof triglyceride，high-density lipoprotein，low-density lipoprotein were evaluatedin all subjects．Results： Plasma concentration of bilirubin were significantly lower inpatients with potential stenosis than control.The severer the intracranial arterialstenosis is，the lower bilirubin concentration in the blood．Conclusion：Low level of plasma bilirubin is closely related to intracranialarterial stenosis．Low concentrations of bilirubin is probably the risk factor ofintracranial arterial stenosis．...
