Abstract: Objective To discuss the characters and the technical strategy of endovascular embolization for aneurysm in cerebral AVM with bleeding.Method 36 cases with cerebral hemorrhage,confirmed by CT,MRI,were diagnosed by cerebral DSA.Depending on the feature of the nidus of AVM and the aneurvsms,the methods of superselective endovascular embolization with NBCA,Onyx or coils for nidus and aneurysms were used.Resuits The aneurusms in 35 cases and nidus in 26 cases were eliminated from 36 cases after embolization.The rebleeding was found in 2 cases.one with draining vein stricture,the others accepted gamma radiotherapy,who were cured by nidus resection or reembolization.Conclusions Intranidal or side-nidus aneurysm were the important causes of AVM bleeding.To prevent the brain from bleeding,it is favourable to formulate embolization strategy to eliminate the aneurysm in AVM preferentially during embolization.
