| Carotid-cavernous fistula Endovascular treatment progress
Treatment of cerebral arteriovenous malformations stupid new show, Nang Nang China calyx Division R, / p;. ZHANG Xiao Huang Xianglong Summary revision I, r Summary Bong article mainly based on recent research AVM embolization catheter choice of embolic material properties and selection criteria of the study, and review the causes and prevention of disease and endovascular therapy in the AVM the status of the treatment, etc. are reviewed. The key to good at tone Kyu Man animal experiments of cerebral arteriovenous abnormal t open; Embolization, therapeutic dance l side comb white and Spenee 1960 Luessenhop first reported by the femoral artery,mbt scarpe outlet, the diameter of 3mm wine container into the neck of plastic balls or steel balls artery, blood flow tend to use the endovascular treatment of cerebral arteriovenous malformation (AVM) has been, AVM embolization therapy has been widely improved,adidas scarpe, and become the treatment of AVM of the mushroom to above. Especially in the past 5 years, basic research AVM embolization catheter choice of embolic material properties and selection criteria of concurrent causes and prevention of defects, and endovascular therapy in the treatment of status AvM and other aspects Many breakthrough. I. Endovascular treatment of AVM of basic research (a) AVM AVM animal model for the mushroom to the relentless profile characteristics is the lack of arterial and venous capillary network Q,timberland shoes, replaced by a vascular malformation of the mission (ie lesions) t to form artery lesions in the blood flow through the rapid flow of venous blood I kinetics. Although it has been reported that use rabbit, cat and monkey as an animal model to study the brain AVM steal and cerebral perfusion pressure breakthrough in the pathophysiology of such disorders, but a lack of animal models of l two features of AVM relentless profile structure - lesions. Lylyk AVM model. Its advantages are: ① easy to make surgery,tory burch outlet, embolization simple. ② economical and ethical. ③ the coagulation system and others similar. ④ meet the AVM anatomy and hemodynamic characteristics. This model of AVM embolization materials, exercises and technical experience as well as access to bolt Mount pathological changes observed after embolization provide r broad prospects. (B) before embolization embolization of brain function in the prediction of Wada and Rasmussen found that intracerebral injection of amobarbital sodium (amyta [) before embolization of brain function as a full secure and reliable prediction test. Since then, amyta [is widely used as a prediction or partial brain hemisphere reagents. . Thiopental dissolved in the 1 / 2 tension in saline solution made of 25mg/ml concentration, that with 30 ~ 50rag thiopental solution was injected into the brain enough to allow superselective produce symptoms of brain tissue without permanent damage left by the optimal dose, and the like mild, continuous short-lived. Therefore,UGG boots Italia, the thiopental exposure of the cavernous sinus surgery is also, in the DSA monitoring wells into the sinus BU will IBCA successful occlusion of the fistula L 』, eliminating the wide variceal _ lead to further risk of bleeding. |
