EVT of a type IIIb MCA-BAVM. A CT showed hemorrhage in the right parietal and occipital lobes extending into the ventricle. B CTA showing that the BAVM was supplied by the M4 segment of the MCA and PCA. C Right ICA angiogram showing that the BAVM was partially embolized via the MCA; the picture in the picture shows the casting Onyx. D Vertebral artery angiogram showing that the PCA still supplied the BAVM, but the volume of the BAVM nidus was reduced. Abbreviations: BAVM: brain arteriovenous malformation, CT: computed tomography, CTA: CT angiography, EVT: endovascular treatment, ICA: internal carotid artery, MCA: middle cerebral artery, M4: fourth segment of the MCA, PCA: posterior cerebral artery, R: right
