title: Normal perfusion pressure breakthrough phenomenon: what still remains unknown.
abstract: We report two cases of normal perfusion pressure breakthrough phenomenon after total brain arteriovenous malformation removal. Hereby, we demonstrate that not only autoregulation impairment in the ipsilateral hemisphere occurs but also contralateral remote vessels response does. Such findings may be observed at 2-4 weeks and may resolve after 1-3 months.
