EVT assisted by the pressure cooker technique. A CT shows frontal hemorrhage above the Sylvian fissure. B-C: Two-dimensional angiogram (B) and three-dimensional reconstruction angiogram (C) of the left ICA show that the BAVM is supplied by the M3 segment multiple draining veins (arrowheads), and an aneurysm (fork in C) on the feeding artery. D Road-map navigation angiogram showing that the aneurysm (fork) has been coiled to create a pressure cooker effect; the tip of the Marathon microcatheter (arrow) is advanced beyond the coils. E Unsubtracted angiogram of the left ICA showing that the volume of the BAVM nidus is reduced, and the draining veins (arrowheads) are patent. E Reconstructive Xper CT showing the location of the Onyx (frame). Abbreviations: BAVM: brain arteriovenous malformation, CT: computed tomography, CTA: computed tomography angiography, EVT: endovascular treatment, ICA: internal carotid artery, L: left, MCA: middle cerebral artery, M3: third segment of the MCA
