Brain arteriovenous malformations cause intracranial hemorrhage. Molecular characterization of lesional tissue implicates angiogenic (vascular endothelial growth factor, ANG-2, matrix metalloproteinase-9) and inflammatory (cytokines and chemokines) pathways, but the pathogenesis remain obscure and medical therapy is lacking. Macrophage and neutrophil invasion has also been observed in the absence of prior intracranial hemorrhage. Common polymorphisms in interleukin-1beta and activin receptor-like kinase-1 are associated with arteriovenous malformation susceptibility, and polymorphisms in interleukin-1beta, interleukin-6, tumor necrosis factor-alpha and APOE are associated with arteriovenous malformation rupture. These observations suggest that even without a complete understanding of the determinants of arteriovenous malformation development, the recent discoveries of downstream derangements in vascular function and integrity may offer potential targets for therapy development. Furthermore, biomarkers can be established for assessing intracranial hemorrhage risk. Finally, these data will aid in development of model systems for mechanistic testing by development of surrogate phenotypes (microvascular dysplasia) and/or models recapitulating the clinical syndrome of recurrent spontaneous intracranial hemorrhage.
