Noncontrast head computed tomography revealed fourth ventricle hemorrhage. Diagnostic cerebral angiography revealed a high-flow midbrain AVM with a posterior wall perforator from the basilar artery terminus and a draining vein into the straight sinus. Transarterial AVM embolization was successful. The patient was discharged with no residual neurological deficits but returned 1 wk later with slurred speech and left-sided dysmetria. Repeat angiography revealed partial AVM filling. Attempts at transarterial embolization were unsuccessful. Thus, transvenous AVM embolization with adenosine-induced cardiac asystole and systemic hypotension was performed. A total of 60 mg of adenosine was administered, followed by 2 additional doses of 60 and 40 mg; and complete cardiac asystole with a mean arterial pressure of 40 mmHg was maintained, resulting in successful embolization of the AVM. No residual filling was visualized on postembolization arterial angiography runs. The patient was neurologically stable and discharged on postoperative day 2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
