title: The Characters of Images and Endovascular Embolization for High Risk Cerebral AVM.
abstract: The high risk cerebral AVM can do great harm to people in case of hemorrhage .The goal of aathis paper is to discuss the characters of images and the technical manipulate of endovascular embolization for high risk cerebral AVM with bleeding. Fifty-six cases of high risk cerebral AVM with bleeding were confirmed by CT?MRI?and approved by whole cerebral DSA. Depended on the nidus of AVM, the superselective endovascular embolization with NBCA or embolization combined with radiological surgery was chosen. 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 following period and treatment with Y-knife, and cured by second embolization. These are the main causes of brain bleeding composed of aneurysm and aneurysmlike dilation beside and located at the nidus, fine draining veins, and growth in ventricles. It is the favourable for the preference to eliminate the aneurysm in AVM during embolization to prevent brain from bleeding.
