BACKGROUND: Leukoaraiosis is common in patients with acute ischemic stroke. The
results from many studies investigating the association between leukoaraiosis and
intracranial hemorrhage after thrombolysis remain conflicting. METHODS: A
meta-analysis was performed to compare the risk of post-thrombolytic intracranial
hemorrhage in patients with and without leukoaraiosis. Relevant reports were
identified by searching PubMed, EmBase, Cochrane Library, and ISI Web of Science
through December 2015 using a combination of subjective and random terms.
Eligible studies that were original articles with a clear definition of
leukoaraiosis and intracranial hemorrhage were selected and analyzed. Funnel
plots, Egger's test, and Begg's test were conducted to assess the publication
bias. Sensitivity analysis was also performed to evaluate the influence of each
individual study. RESULTS: Eleven trials that enrolled 6912 participants were
included. There was a significantly increased risk for acute ischemic stroke
patients with leukoaraiosis (odds ratio: 1.89, 95% confidence interval 1.51-2.37,
P<0.001). Low heterogeneity and less publication bias was detected among these
studies. The results of both computed tomography and magnetic resonance imaging
performed on the subgroups of leukoaraiosis were significant. Furthermore, an
association between leukoaraiosis and symptomatic intracranial hemorrhage was
also confirmed. The odds ratios remained stable with no obvious variations on the
sensitivity analysis. The limitations consisted of types of including trials and
not matching some baseline variables. CONCLUSIONS: The results of this
meta-analysis show that leukoaraiosis approximately doubles the incidence of
intracranial hemorrhage after thrombolytic therapy. However, it does not
critically affect decision making regarding thrombolysis for patients with acute
ischemic stroke. Additional investigations are required.
