Abstract:
Objective To investigate the association between silent intralesional micro-hemorrhage (SIM) and symptomatic intracranial hemorrhage (ICH) of brain arteriovenous malformations (bAVMs) by using evidence of old hemorrhage (EOOH) and hemosiderin dyeing results.Methods Sixty-three patients with bAVMs,admitted to our hospital firom September 2014 to September 2016,were chosen in our study;their clinical and pathological data were retrospectively analyzed.Logistic regression analysis was performed to assess the correlations of ICH of bAVMs with EOOH and Prussian blue staining results after adjusting the factors as gender,age,lesion size,location,single or multiple supplying arteries and deep venous drainage.Results Gender,age,lesion size were not associated with ICH of bAVMs,while single or multiple supplying arteries,deep venous drainage and SIM were significantly associated with ICH ofbAVMs.EOOH and Prussian blue staining results were the independent predictors of ICH ofbAVMs (OR=5.507,95％CI:1.208-25.111,P=0.028;OR=6.055,95％ CI:1.479-24.793,P=0.012).Conclusion ICH of bAVMs could be proved by EOOH and hemosiderin,and EOOH could serve as a potential predictor ofICH ofbAVMs.
