Abstract:
Objective To discuss the image characters and the technical manipulation of endovascular embolization for cerebral AVM with bleeding. Methods The cerebral AVMs with bleeding in 56 cases were confirmed by CT, MRI, and whole cerebral DSA. Depended on the nidus of AVM, the superselective endovascular embolization with NBCA or embolization combined with radiological surgery was chosen. Results The nidus was eliminated for 100% in 36 cases after embolization for 1 to 3 processes. The rebleeding was found in 2 cases with new growth and survival aneurysm in nidus during the follow-up period and treatment with X-knife, and was cured by the second embolization. Conclusion The main causes of AVM bleeding included aneurysm and aneurysm-like dilation beside and located at the nidus, fine draining veins, and growth in the ventricles. To prevent the brain from bleeding, it is favourable to eliminate the aneurysm in AVM during embolization.
