Research on the Safety and Efficacy of Blocking Dural Blood Supply in Glioblastoma Patients

"The embolic agent used in bilateral meningeal blood supply occlusion through interventional surgery is Onyx glue (liquid embolic system). After the location of bilateral middle meningeal artery was determined by femoral artery puncture angiography, SL-10 was sent to the opening of bilateral middle meningeal artery through guiding catheter, and Onxy glue was used to block the bilateral middle meningeal artery. The standard of embolization was that the middle meningeal artery was not seen and Onyx glue was not diffused to the petrous branch of the middle meningeal artery. In order to avoid dangerous anastomotic branches and complications, attention should be paid to superselecting the middle meningeal artery and slowly injecting Onyx glue during the operation. After embolization of the middle meningeal artery by interventional surgery, glioblastoma was removed immediately under the guidance of multimodal imaging."
