RationaleThe hybrid surgical concept for the treatment of brain arteriovenous malformations (AVMs) with associated intracranial aneurysms (IAs) is still not widely practiced. Concomitant occurrence of AVMs with IAs is common. Subarachnoid hemorrhage (SAH) as a result of AVM or IA rupture is often associated with these dual pathological phenomena. We present a case of concomitant occurrence of AVMs and IAs that was successfully treated using the hybrid operation concept.Patient ConcernsA 62-year-old man presented with sudden onset of severe headache, dizziness, nausea, and vomiting for 4 hours.DiagnosisComputed tomography revealed SAH and a hematoma in the right frontal lobe. A computed tomographic angiogram also revealed a right frontal AVM with 3 IAs.InterventionsWe used a hybrid operating room to successfully treat both AVMs and IAs.OutcomesTwo years of follow-up showed that the patients were well and performed their daily duties.LessonsThe hybrid operating room is an innovative, safe, and effective method for the treatment of AVMs with associated IAs, particularly high-grade AVMs and IAs with hemorrhage or SAH. Patients with concomitant AVMs and IAs have the highest chance of hemorrhage compared with those with AVM or IAs alone.Copyright © 2022 the Author(s). Published by Wolters Kluwer Health, Inc.
