Figure Lengend Snippet: A “typical” WAVES case. A 65-year-old female with sigmoid colon cancer with liver metastases received TACE via WAVES. Multiple hypervascular tumor stains were noted on both lobes of liver, and blood was supplied by the left hepatic artery (LHA), middle hepatic artery (MHA), and right hepatic artery (RHA). A Superselection of the LHA, MHA, and RHA was accomplished by using the WAVES technique with 2.4-Fr. Merit Maestro microcatheter ( B - D ). Cone-beam CT was used to help identify both the target vessels and area of the liver that was covering the tumor(s) ( E )

Article Title: Onyx embolization of a cerebellar arteriovenous malformation fed by the posterior inferior cerebellar artery originating from a vertebral artery fenestration: illustrative case

doi: 10.3171/CASE25790

Figure Lengend Snippet: Angiographic findings before and after embolization and resection. A: Preembolization right VA angiogram showing an AVM in the right cerebellar hemisphere, mainly fed by the right PICA originating from the lateral limb of the VA fenestration ( arrow ). B: Contrast injection from the Marathon microcatheter ( arrowhead ) advanced to the distal right PICA, demonstrating the AVM in the right cerebellar hemisphere. C: The Onyx cast visualized before withdrawal of the Marathon microcatheter ( arrowhead ). D: Withdrawal of the Marathon microcatheter ( arrowhead ) from the Onyx cast while preventing the 4.2-Fr Fubuki DAC from moving forward. E: Postembolization right VA angiogram showing near-complete obliteration of the AVM. F: Postresection right VA angiogram demonstrating complete disappearance of the AVM.

Article Snippet: Using a Phenom 27 microcatheter (Medtronic) and a Chikai 14 microguidewire (Asahi Intecc), we navigated a 4.2-Fr Fubuki (Asahi Intecc) as a distal access catheter (DAC) to the proximal portion of the VA fenestration.
