Summary

Brain arteriovenous malformations (bAVMs) are rare aggressive vascular malformations affecting mostly young and healthy adults. The most frequent revealing condition (in almost 50% of cases) is an intra-cerebral hemorrhage, which is a considerable source of disability and mortality. The only way to prevent a bleeding or a rebleeding is to perform an exclusion treatment (endovascular embolization, microsurgery, stereotactic radiosurgery, or a combination of these techniques). The major drawback of these treatments is the risk of severe complications, which can reach 20%, especially in patients presenting a bAVM with complex angio-architecture (i.e., grade IV to V in the Spetzler Martin grading scale). There is a growing evidence about the strong implication of angiogenesis (mainly mediated by the type A vascular endothelial growth factor \[VEGF-A\]) on the size and growth of the bAVM and even in the occurrence of bleeding events. Our hypothesis is that an in situ injection of bevacizumab, a monoclonal antibody inhibiting VEGF-A, in patients with bAVM deemed not suitable for exclusion treatment may be safe and help to reduce the nidus volume.
